Different Swisstool plier heads , the truth
on: October 09, 2007, 07:57:38 PM
Many of us on here have wondered about why the pliers on the Swisstool have changed , for instance in this picture by Jsews  ( Bob )


Well all this talk about the pliers and no real answer prompted me into emailing Mr Robert Elsener from Victorinox . I have asked him questions in the past and he has always been very helpfull and quick to reply . Well this time is no exception with a full explanation .....

Dear Mr Moore

 

Thank you for your mail dated 07th October 2007 and being interested in our products. We are pleased to answer your question.

 

All adjustments (fixing) made on our «SwissTool» and «SwissTool Spirit» are recorded and valuated by our customer service. By means of this analysis we are able to optimize the quality and functionality. Your question about the pliers' construction details has been discussed on an Internet forum some month ago. A user mentioned a theory what exactly nailed our intention.

 

 

If you twist a pair of pliers in either direction, the maximum torque until breakage is different. Most pliers are less strong when you twist something counter-clockwise, as if you were trying to loosen a bolt or remove a screw. Counter-clockwise tends to spread the pliers tip apart, whereas clockwise twisting will force the pliers half against one another and be stronger. That's the reason why we reversed the pivot on our SwissTool and SwissTool Spirit new pliers head design.

 

If you require any further information please do not hesitate to contact us.

 

 

Yours sincerely



VICTORINOX

But the best bit is this picture he sent . Feast your eyes on this



It really makes sense doesnt it , you are far more likely to crank down hard on a frozen nut or bolt to get it undone but mostly when doing a nut up you stop when its tight and dont keep applying pressure .

You may need to scrole to the right on the picture to see the 2005 model as its really wide

Most excellent work dunc! That means mine is a 1998 model, very nice to know. The 2005 model looks much chunkier than the original....and thats saying something!

Another great side-effect of Lifetime Warranty. Vic has every incentive to make sure things do not break easily!  ;D
Great job on the enquiry, and the picture is great, probably should be uploaded to SAKWiki under Pliers section...

Cool pic Dunc! And very nice that Vic would humor us MT-nuts :D The new design makes sense to me for the reasons you said. A side question... Anyone else think the pliar design looks less and less LM-ish as the years go by?

Yes very much so , I guess over the last few years Vic has been working out ways of improving the design and although the original folding plier design is credited to Leatherman ( although some may dissagree with this ) vic has been doing its own thing .
  Notice how with the exception of the spirit how Victorinox keep improving the existing design without the need to keep bringing out new models each year like some companys which 90% of all do the same thing but just dressed in new clothes .

Now that I think about it, LM's and Vic's pliars made at least similar change since 97. They both widened the pivot area, although they look more different now since LM's is more oval while Vic's is more stocky and squared-off. Must be a good idea if both companies are doing it :)

Although LMs still hinge the other way to the newer Vics .

The new design makes sense to me for the reasons you said.
Sorry to quote myself :D but the more I think about this the more confused I'm getting.

Most pliers are less strong when you twist something counter-clockwise, as if you were trying to loosen a bolt or remove a screw. Counter-clockwise tends to spread the pliers tip apart, whereas clockwise twisting will force the pliers half against one another and be stronger.
This still makes sense to me in an intuitive way, but I'm having a hard time wrapping my brain around the physics of this. Can anyone help me out?  ???

I did a crude drawing of how the forces apply to the plier jaws. You can see that when the "top" jaw is on the "left" the forces squeeze the jaw arms together on the counter-clockwise motion. Of course, the preferred approach is to use the pliers as a wrench, in which case the arrangement of the jaws does not matter...

Thanks for the picture. I was picturing the pliars parallel to the bolt head, not perpendicular. Makes more sense now :)

Great post dunc. Very interesting to see the pictures of all the different plier heads.

Sounds like Victorinox are damn good when it comes to customer services. I've never had to use them as I haven't had one break but it gives you a lot of confidence to know what they're like  :)

Great sketch ufox9al, that really demonstrates the theory well!

BTW, I'd like to add some plier-head details to the SwissTool page at both SAKWiki and the Multitool Encyclopedia. If you don't mind, I'd like to use your sketch at both sites.
