A better Leatherman, Tim Leatherman?
Tim Leatherman deserves all the credit for creating a new category of tool back in the 1980s. If it was not for his insight, creativity and persistence, the world would not have the ubiquitous tool bearing his name.
Everyone familiar with the brand knows how Tim was inspired to design a pocketknife that contained pliers while touring overseas with his wife in the mid-70’s and attempting to use a scout pocketknife to repair a malfunctioning Fiat and leaky hotel plumbing. But there’s an interesting back-story to the early-days of Leatherman’s success that’s maybe not as well known.
Tim’s original plan was to build a prototype, patent it, and sell it to a knife manufacturer for a million dollars. He never intended to create his own company. Tim liked to do things himself (remember the hotel plumbing?), and along with building the prototype in his brother-in-law’s garage (aptly named 'Mr Crunch'), he even started to author his original patent claim, before contracting a patent attorney.
Patent US4238862 was granted to Tim in 1980. Many people believe this patent, stamped on the side of the original Leatherman tool, relates to Tim’s concept of having a pair of pliers with folding handles. Unfortunately, Tim was unsuccessful in patenting this idea, as the patent office said that scissors, which fell under the same hand tool classification, already existed with folding handles. However, the patent office agreed to cover his unique clamping feature and the combination of two kinds of pliers connected by pivots.
Maybe young and naïve, Tim’s efforts to sell his “knife with pliers” to various knife manufacturers all failed. It took eight years of effort to get his first deal, 500 units from the mail order catalog company, Cabela, but only after deciding to manufacture the product himself (partnering with his friend Steve Berliner, who’s dad had a metal-fabrication business), and after the first catalog company they approached, Early Winters, suggested they simplify the design to reduce the price-point by ditching the complex interlocking twin plier heads and the costly scissors.
Following that first order from Cabela in May 1983, Tim and Steve agreed to formalize their business. Steve insisted the company should be named after Tim, and so the Leatherman Tool Group was registered in July of the same year. Tim moved his equipment from the garage to Steve’s dad’s factory, subcontracting a few of the staff to start production. Probably tired of being seen for years as a one-man-show, Steve and Tim chose the name “Leatherman Tool Group” to make themselves sound bigger than they were. Ten’s of millions of tools later, it probably was a wise choice.
But what about that original patent? It only appeared on Leatherman’s tool for the first couple of years of production. Leatherman filed for a registered trademark of the word “LEATHERMAN” in 1984, granted in 1985. Unlike patents, active trademarks do not expire. However, Leatherman has had a tough time defending against companies copying their designs. And while his original 1980’s patent has expired, in 1999 the 9th U.S. Circuit Court of Appeals ruled that competitors can "faithfully copy" Leatherman's all-in-one pocket tool without violating his trademark. Looking back, Leatherman admits that he should have originally tried for a design patent. However, the tool that launched the company had already evolved beyond the original patent, and alternative patents would have expired.
But there is an alternative folding design. Possibly a better design, and one that Leatherman themselves adopted with the launch of the Wave in 1998. This design, patented by Bear MGC Cutlery in 1996, describes a folding multi-tool with tools that can be deployed while the tool remains closed. And when opened to use the pliers, the channel-shaped handles face inwards, with rounded edges for greater comfort. The multi-tool listed in Patent US5697114 looks near-identical to the original Leatherman, except for the handles that are rotated to face outwards. The Bear Jaws 155 (with "patent pending" stamped on the handle) was recognized by Blade Magazine in 1995 as the most innovative new multi-tool on the market. I’m sure that Tim Leatherman must have said “why did I not think of that!” when he first saw the Bear Jaws tool.
Contrary to most references on the Internet, Victorinox did not buy Bear MGC to acquire the patent for outside-opening blades, first used by Victorinox on their 1997 Swisstool. It was Victorinox's US Distributor, Swiss Army Brands, Inc. ("SABI"), that acquired Bear MGC Cutlery, Inc. in April 1999 for $7m. However, the purchase excluded certain patent rights, which were made available under license to SABI.
According to Ken Griffey from Bear MGC Cutlery, when SABI brought the European-designed Swisstool to the US, he decided to sell his business to SABI rather than enter into a long and costly patent infringement case with a large US company. There’s also no truth to the account that Victorinox acquired Bear MGC for their multi-tool expertise. Ken was quoted as saying "The Swiss executives came down to see the factory exactly once. They never came back."
Ken Griffey stayed on to run Bear MGC on the back of a multi-year performance incentive. However, a year after Victorinox acquired all the outstanding shares of SABI in 2003 (taking full ownership), they sold Bear MGC back to Ken, who renamed it Bear & Son Cutlery. The company continues to manufacture, and even rebrand, the original Bear Jaws range of outside-opening blade multi-tools. Although the 20-year old designs are now a little dated.
Did Tim Leatherman recognize the Bear Jaws as a better tool, ahead of its time? Two things may point to this suggestion. Firstly, the new and ever-expanding range of Leatherman tools adopting the outside-opening blade design since 1998. And secondly, if you look again at the Bear MGC patent from 1996, the current assignee is non-other than Leatherman Tool Group Inc.

wow that was a great read, thanks so much

Thank you for the post, Max! I had always avoided the claim than Vic bought Bear for the patent, because the dates did not work for such a purpose. Your information if much appreciated. :)
Bear really did change the MT game with the Jaws series though. They aren't refined and fluffy with extras, but they are rock solid and reliable. The poor tolerances have the benefit of functioning for eons without a cleaning, while Vic's designs require careful use to not expose it to metal dust and dirt(since it'll lock up rather quickly).
The SwissTool is a better tool for most people, but the Bear Jaws is what you want in a messy/dirty work environment. :)

Thanks for the feedback and additional info. I enjoyed doing the research!
I have a ‘95 BJ so can attest to the robustness and relaxed tolerances. May just do a review one day and a comparison to my PST and Rebar. I definitely have a preference for the ‘classic’ styles...
Cheers, Max

:cheers:
Will definitely be looking forward to a review of an early Bear Jaws. Thank you again for doing the leg-work, Max!
I have a soft spot for Bear Knives and MTs, as they are produced in my home state. But, that said, I can objectively look at them and am aware of where Bear needs to improve. Mainly, the locking system on the 'L' locking tools. They need to grind the lock lever tang bump down to where it is about flush with the handles. And for goodness sakes, Bear, lets get the QC tightened up. :ahhh

Great read
Has the Bear patent expired? Maybe LM could release a PST with reverse handles.

Probably 14 years, so expired 2010. Outside opening PST sure would be cool! There are some design limitations that I’ll cover in my review. Will try to get it out by the weekend...been busy modding the lock tab hinges on my Rebar...

So this is not a Leatherman review, but I know there are people on this forum that collect multi-tools, and the Bear Jaws is a historically-relevant first-generation multi-tool that deserves a closer look.
It’s a bit of a ramble and 2,000 words, so I’m going to release this review in 3 sections to also add some pictures.
Bear Jaws 155 Review (part 1 of 3)
Bear MGC Cutlery started in 1991, when former employee Ken Griffey bought the Parker Edwards facility in Jacksonville, Alabama, that was scheduled for closure. He sold the business to Swiss Army Brands in 1999, staying on to manage it. Ken bought it back in 2004 after Victorinox took over Swiss Army Brands, running it with his son, Matt, as Bear & Son Cutlery.
In 1995, and prior to the Swiss Army Brands acquisition, Bear introduced the Bear Jaws 155, a multi-tool with outside opening tools. Nothing we would not recognize today, but quite revolutionary for a multi-tool in the mid-90s. So much so that it was nominated as the most innovative new multi-tool on the market by Blade Magazine in 1995, and Bear MGC was awarded a patent for it in 1996.
At the time, Leatherman was ripping-up the multi-tool market with million-plus unit sales across only three models. The original Leatherman PST was the industry benchmark, to the point where Leatherman had successfully taken on over a dozen competitors legally for copying their design.
With their own patent, Bear MGC had a little more room to go head-to-head with Leatherman’s market-leader. Visually, the 155 mirrors many elements of the PST. It was the same 4” length with polished, straight-sided stainless channel handles, near identical pliers and near identical plain-edged blade.
But the significant design difference of reversing the C-channel handles gives the 155 a much more comfortable grip when using the pliers, a clear advantage over the PST. In fact, this feature alone kills the PST dead in any hands-on comparison. The 155 is a good example of coming late to market with a better design, but hopelessly behind the sales and marketing momentum of the market leader. Bear MGC was successful in rebranding the 155 for several companies, including Crescent, Sears and LL Bean, but they were never a threat to Leatherman’s market dominance.
Bear MGC added a locking mechanism to the 155 in 2001 (155L), and this model continues to be manufactured by Bear & Son Cutlery, along with smaller and larger versions (mirroring the LM Micra and Super Tool). As second-generation multi-tools, these Bear designs are now a little dated, but worthy of the recognition they deserve.
The example under review is an early-generation 155, stamped “patent pending”, dating it to 1995 or early 1996. I have a pre-date stamped, post-metric Leatherman PST that I will use as a comparison. While the PST is older, it is the model Bear MGC would have referenced when designing the 155. This is obvious when comparing these two products.
First impression is the greater heft of the 155. At 199g (7oz), the 155 is a significant 49g (1.7oz) heavier than the PST. In fact, the 155 has a similar weight to the modern 4” Leatherman Rebar that weighs in at 188g (6.6oz). In fact, the 155 and Rebar are visually and dimensionally a close match.
The main reason for the additional weight is the thicker gauge steel and the beefy tools. The 155 handles are made from heavy 16-gauge steel (0.06in), compared to the PST that uses only 20-gauge steel (0.03in). Today, Leatherman does not even use this thick gauge steel in their largest multi-tool, the Super Tool 300. There’s no doubt that the extra weight contributes to the perceived robustness and quality of the 155.

Bear Jaws 155 Review (part 2 of 3)
Visually, the 155 is polished to an almost mirror-finish. Turning the 155 in your hands reveals its party-trick; the outside-opening tools. There’s no doubt that this patented feature gives the 155 a real advantage over the PST. While it’s not possible to open a tool with one hand, it’s easy to quickly select and deploy any one, with no handle or plier head to get in the way.
But there are a few unwanted consequences of reversing the C-channel handles to face outwards. The first consideration is that more dirt will enter and get trapped between the tools compared to the PST that closes around its tools. The second consideration relates to the geometry of the tools relative to the plier head. Because the plier head enters the handle on the opposite side to the tools, the 155 needs a stop plate midway inside the handle to prevent the head dropping through the handle and pushing the tools to the outside. These stop plates take up valuable space and are not needed in the PST where the plier head can push up directly against the tools, and everything folds up against the spine of each handle.
The 155 sample I have does not keep a tight closed position, which appears to be a result of the plier pivot-handle geometry. Maybe they fixed this in later versions, or maybe not, as it would require a retool of the head or stamping of the handles. Either way, this is a small design quirk that gives the 155 a little bit character that matches its slightly industrial feel.
Turning our attention to the plier head, it looks like it came out the same factory as the head on the PST, but looks can be deceiving as there are some significant, and possibly critical differences.
The 155 and PST plier heads are both 56mm (2.2in) long, and the profile of the 155’s head is a clear copy of the PST, with near-identical needle-nose, normal pliers and wire cutters design. The 155’s head is slightly narrower (by 0.3mm, 1/100in), because the head has to drop through a gap between the rolled edges of the handle, while the PST has no rolled edge where the head folds back into the handle, so is overall a lot thinner across the handle (11.7mm vs 14.8mm / 0.46in vs. 0.58in).
The 155 has a little more flex visible around the plier’s central pivot under load, more than can be explained by the slightly narrower (lower cross section) design alone. The longer pivots that link the plier head to the handles may be creating additional flexing under gripping load, but it’s also easier to apply much more grip pressure with the 155 because of the wider and more comfortable handles.
While we’re on the handles, the 155 uses standard torx button-head screws to secure the pivots, making user servicing a lot simpler that the knurled rivets Leatherman uses on the PST, and to this day on many of its multi-tools. The plier pivots of the 155 span an outside surface distance of 13.2mm (0.5in), which is a little more that the PST pivots that only need to span a distance of 9.3mm (0.35in), so theoretically, stronger.
Like the Leatherman PST, the 155 has ‘USA’ cast into the plier pivot, but facing outwards. ‘MADE IN USA’ is also stamped into the handle, long before the rule regarding material/component sourcing made this mark a little more difficult to use.
The ruler stampings are clear and sharp, and because of the thicker gauge steel, more stable than those on the PST that tend to distort the surface. Also, the 155’s metric and inch rules are on opposite sides of the handle, making it a lot easier to read off the markings compared to the PST that squeezes both scales on the narrow spine (in my sample).
(…the final part will follow tomorrow)

Bear Jaws 155 Review (part 3 of 3)
While Bear MGC changed the handle/plier pivot bolsters in later designs, this early 155 reviewed here features the welded ends that secure the pliers. This is another consequence of the outside-facing C-channel handles, as the plier head would otherwise have nothing to stop against when opening. Bear MGC lapped a short, reversed C-channel section to capture the plier mounting points and provide a hard stop when folding open the multi-tool. The PST has no need for this additional piece of metal, as the spine of the C-channel handle forms the stop, as it does for all similar Leatherman designs.
While the plier heads are close copies, the tool loads are quite different:
Bear Jaws 155 Leatherman PST
PE Knife Yes Yes
SE Knife Yes No
File Yes Yes
Phillips Screwdriver Yes Yes
Small Screwdriver No Yes
Medium Screwdriver Yes Yes
Large Screwdriver Yes Yes
Awl No Yes
Bottle/Tin opener Yes Yes
Lanyard Folding tool Outside on rivet
The folding tool count is 8 on each, however the 155 has the advantage of the wider handle that can accommodate longer tools both sides of the plier head in both handles, while the PST is limited to just one long tool per handle, as the handle only widens asymmetrically on one side.
Comparing the PE blade, they are both near identically shaped clip points 67mm (2.6in) long, although the PST is very slightly thicker. Both hollow-ground, while the PST is better finished with a higher polish. None of the tools lock, however the 155 has the more positive detent – most likely a result of the stronger spring, a consequence of the thicker gauge metal. In fact, Bear MGC added a hole to the handle in later versions to reduce the high spring pressure.
The SE blade on the 155 is a chisel sheepsfoot with combo-edge (a repeating pattern of one wide serration followed by two thinner serrations), a very close match to what’s found on the modern Rebar.
The file appears coated and has a fine pitch, single-cut on one face and one edge, and double-cut on the second face. The tip is squared-off (cut as opposed to stamped-off like the PST). Thickness is about the same in both, around 1.8mm (0.07in).
The 155’s Phillips screwdriver is a serious chunk of cast steel, taking up 7mm (0.27in) of the pivot base and serious overkill. This is a full three times wider than the Phillips on the PST and undoubtably the strongest Phillips driver I’ve seen on any multi-tool, ever. The Phillips tool is so wide, there’s only room for a knife on one side and the tin opener on the other. The tool ‘stack’ is 11.8mm (0.46in) per handle, which is easily a tool width more than the 9.5mm (0.37in) of the PST. Incidentally, the 155 stack is almost the same as the Rebar’s 12mm.
The tin opener is a standard affair, but with a sharply milled edge and sharp tip that will pierce bottle tops. The medium and small screwdrivers are standard 5.3mm and 7.3mm drivers (0.2in and 0.3in), similar to the PST and similar 2.3mm thickness, but the 155’s medium driver has less reach (30mm/1.2in), by 5mm (0.2in). What the 155 lacks is the PST’s small screwdriver that tapers to a tiny 1.8mm (0.07in) blade size, fine enough for glasses.
The 155 is also missing the awl found on the PST. Something they could easily include if they reduce the generous width of the Phillips tool to a more standardized size. Even though Bear & Son continue to manufacture the 155 (in locking 155L format), the features and design remains faithful to the original, and they market it as having 18 functions. But using Leatherman’s more conservative tool count, the 155 has a low 12 tools compared to the PST’s 13 (pre-hardwire notch).
Strangely, Bear MGC saw fit to include a folding lanyard strong enough to lift a small car. The lanyard matches the full internal height of the handle (12.5mm, half-inch), and 2.3mm (0.09in) thick. The lanyard hole is almost 5mm (0.2in) diameter, so with a 4mm steel cable, you could support over one ton of weight on this lanyard! Positioning the 155’s two handles into an ‘L’ makes it a good pulling tool, like you find on some SAK products. By comparison, the PST’s lanyard is a small stamped affair included under one of the knurled rivets, just large enough to take a split-ring. To be honest, probably nothing more than you need. As a side-note, if you open the 155’s lanyard tool and attached a cord or split-ring, the adjacent screwdrivers cannot open fully – oops!
So do I think Bear MGC made a winner? Yes, in its day. The Bear Jaws 155 appears over-engineered with enough tool gaps and escape holes to ignore dirt and grime and keep working. What initially appears to be just a Leatherman clone is clearly an effort to offer an improved product. Stronger, easier to use and more comfortable, yet still immediately identifiable as a full-size tool in the tradition of Tim Leatherman’s first PST.
Now I wonder if Ken and Matt’s current Bear Jaws 155L lives up to its vintage predecessor?
Footnote: Let’s see your Bear If you have one (or more)! What are your impressions?
-
An excellent finale. Thank you again, Max! :like:
It seems Bear addressed two of the issues since the early tools. Added awl instead of SE blade and reasonable lanyard loop that moves far enough out to allow drivers to be used.
(http://i.imgur.com/vK1Q3uB.jpg)
Edit:
I should add that Bear shortened the usable area of the file(to save money on machining I guess). The lock levers would be a good system if they would grind the lever tang-bumps down enough to have them level with the handle edges. I may do this to one as an experiment at some point.
