Are LM OHT and Wave/Charge knife/saw interchangeable?

[ioch]

Will the knifes/tools from OHT work in Wave or Charge? and vice versa?

[JAfromMn]

As far as I know nobody's tried.

The tools from the oht might fit inside a wave but I don't see wave tools fitting in a oht.


I truly don't know.  Good question ioch

[Kampfer]

I installed the wave blade on OHT tonight, it fits perfectly with solid lock up.
But few issues:
1. The flathead which share the same slot with blade must go to different place.
2. The tip of blade is expose through scale, I think it is safe (only time can tell) but it looks extremely dangerous.
3. I replaced the can opener with flathead came from the othe slot. but the finger grove, liner detent ended up on the wrong side, not too big of a deal. can be easily address.

Overall, I think it can be done with a little work.
But I restored my OHT back the way it is.

[ioch]

Maybe the serrated blade will fit better with less sharp edge sticking out?

Do/how the OHT blades fit on wave?

[rdub934]

Interesting. Please do it again and take some pictures! lol

I have always been curious about Surge parts in an OHT. Since they are both 4.5" tools I figured they would work. An OHT with a respectable blade and those honking huge scissors would be awesome-sauce.

Ok i will

[Kampfer]

Ok let's take a closer look.
First, I un-install both can opener and large flathead.
Comparing them side by side, you can see they share the same pivot & overall size. However their detent, finder grove and their locking surface are opposite, because they came from the opposite side of OHT. If you install large flathead in place of can opener without any modification, the flathead will not lock.   

Second, let's compare the blades from Wave and OHT.
Other than the obvious different length & shape, they are mostly identical.

[Kampfer]

Let me install wave blade in OHT and see what happen.
Wow, it works, lock up is solid, smooth opening, smooth closing...but

[Kampfer]

The tip of wave blade is sticking out from the scale like a sore thumb, looks extremely dangerous. (that itself already is a deal breaker for me).

To conclude, as a "drop in" mod, you will either give up the large flathead, or lose the can opener and have a non-locking large flathead.

But with some TLC, I think it is possible to overcome all the issues and complete the mod with flying colors.
However I am not pursuing this.

Interesting....I have lots of wave blades...maybe a SLIGHT reprofiling will make the tip less exposed, but would it make it the same length as the regular blade on the OHT?

I was thinking pretty much the same thing... I would love a longer blade on the OHT, but if you reprofile the Wave blade enough such that the tip is no longer exposed, I'm guessing it will end up roughly the same size as the original OHT blade.

thanks for the pics, Kampfer!

[mapletaffy]

Thanks for trying that and posting pics. I got an oht recently, tommorow I'm going to try putting a 108mm victorinox blade. Looks long enough to keep the point out of the finger groove. I'll update later.

Also does anyone know if Home Depot sells torx security bits?

That's why I was thinking Surge Blade. Longer, so maybe the tip will be beyond the opening? Also, another option would be to put the serrated Wave blade - it doesn't have the drop point style blade tip. That is an interesting thought in it's own right. Get the serrated + gut hook blade from a TTi and you could lose the dedicated strap cutter from the OHT, and maybe keep the OHT's PE blade. Ooooo, the possibilities are endless really.

A MUT combo blade! Replaces both the PE and SE blades from the OHT.

[rdub934]

BTW, thanks for doing that and breaking it down for us, Kampfer! Really cool!

[Kampfer]

the serrated Wave blade 's edge will be facing up, still expose, i tried it.

If we can mod the scale, then there will be a lot we can do.
Maybe a add-on insert for the scale.

It is actually safer than it looks, i rub my finger on the tip and didn't get cut, thanks to the liner lock prevent finger getting deep enough to get cut. (I don't know how to explain it).

[Lichtbote]

Is there any chance you can show a pic/pics of that?

A longer serrated blade and a longer saw are my main wishes for my OHT. 

[Kampfer]

Not my photo, but you can imagine the edge of SE blade on the outer side of the tool. Not a problem on Wave charge surge, but if it is expose, it could dangerous.

BUT, I forgot to take in consideration of the SE blade is sheepfoot, so the tip "might" be postilion under OHT's scale when folded.....
Sorry I dont have OHT with me so I can not try it.

If it isn't, one could take a little off the blade rest to drop the end.

[Lichtbote]

I only have the Surge, and i assume it´s se-blade will be to big around the pivot, so i can´t give a educated guess about the fitting of a Wave blade in my OHT.

But comparing the small OHT serrated and the big Surge serrated, shows they are both ground the same way. If the Wave serrated is ground the same way (it looks identical on pics), too, it begins to be really interesting - additional it is placed in a slot on the opposite side on the OHT, so the sharp edge is even more to the middle of the tool. 

It all comes down to if the pivot fits and if the blade could be folded parallel to the bottom of the slot.

I have been doing allot of trial mods lately, but with the exception of upgrading steels, I always go back to how it was. After a long wait I did the old switcheroo with the Wave and Rebar plier head and then changed back. I am about the tackle the Mut mod however.

A minor victory for me was getting the strap cutter from the OHT on the wave. It even "clicks" dammit! But not a perfect fit due to the sloping of the area the blades rest in the closing position. This would have been my (near) perfect tool. Having said that I only decided to move it off the OHT after finally getting to use the strap cutter and being totally disappointed it its performance cutting clothing away from a patient. This resulted in me rotating the OHT off on-duty EDC.

Personally I kind of like the OHT blade. In fact I think it would be almost the perfect tool for an emergency tracheotomy in the absence of a scalpel. Its also less intimidating than say a Surge blade when you whip it out in public. And considering you have the sheeps foot blade as well I think its a nice combo. Perhaps one large blade that could do both would be neat. But only tool I would be willing to ditch would be the can opener. If you get rid of more than that IMHO it's looses its appeal as they didn't really give you a whole lot of tools in the first place.

[Lichtbote]

I plan to keep the mini plain edge blade - for the reason you mentioned, a nice small and pointy blade, and it´s not intimidating.

To get a bigger saw and a bigger working blade (serrated sheepfoot) i only need to give up the small flat screwdriver for the bigger blade, and for a bigger saw the can opener. I could live with that easily on my edc MT, as i don´t need any of them.

[Cupboard]

I'm now wondering if it's possible to put a file in...

[TheDude]

Yeah I guess the little screwdriver won't be missed Litch.
CB I feel your pain. What about a hack saw blade?

[Cupboard]

Maybe using a Surge blade exchanger somehow?

[Lichtbote]

I was curious - and while waiting if TexasTC has some parts in their stash i could get, i dissasembled the fixed saw from a knockoff of a old style Leatherman. So it doesn´t really fits, and i did no grinding on this test to be able to put it back - but it worked good enough that it could be used that way already. It´s noticeable longer, and while from a cheap knockoff it makes a very agressive cut.

The saw is kind of a slipjoint atm, not locked. It would be easy to flatten the now rounded back of the saw to make the OHTs lock working (but i need the round when i put it back in the tool it came from).

While protruding the can opener could even stay without problems, it still fits into the Molle sheat - it´s just looking a little bit strange. As mentioned, i did no grinding to it, it´s just a first test. You can see on the pics that there is a hump on the underside of the saw, where the saw edge meets the pivot area. That makes the tip of the saw staying "in the air" (visible at the cutout) instead of going all way down the slot - would i grind the hump down, the tip would go deeper and the can opener could also go back deeper into the slot. Probably some additional re-profiling of the saw tip and the back of the can opener could be done, to make it less sticking out, too.

This test makes me even more thrilled for the mod, i hope to get my hands on a BO saw and serrated blade soon.
