That would negate the :spyder: hole, no! :confused:

i was under the impression that the UKPK was a friction folder. there's also the rare earth magnet folder coming soon.

Anyone want to explain a friction folder to me?

I'm of the mindset that if it doesn't have a lock, it's a slipjoint. Could someone enlighten me as to the difference between a slipjoint and a friction folder? :confused:

I beleive that a slip-joint always relys on a spring, pressing against the edge of the tang to hold the knife both open and closed. Whereas a friction folder relies, in effect, on a very tight pivot to "squeeze" the sides of the frame against the sides of the blade tang to keep the knife closed. That pressure is often augmented by some other means of keeping the knife open, so it will not close unexpectedly. The split ring on an Opinel, or in the case of the knives above, the "finger" coming off the back of the tang.

Doesn't seem like a very good idea. I would think a friction folder would loosen up MUCH faster than a slipjoint.

I must be missing the appeal... :confused:

I'm not sure but I think Deacon's pretty much covered it, tight pivot pin and the long piece of steel prolonging the tang of the blade which is supposed to go in the spine the knife and will be blocked by the hand. this kind of "lock" is made for a cutting only in a normal grip position.

Hi,

during Eurosatory, three weeks ago, I have given a friction folder to Olive for her to give it to Sal !
It's a Xavier Conil piemontais knife called "Couteau Des Sorgues", designed 10 years ago. The blade looks like the Chinese folder and cuts like a devil.
I love that knife so much, I took my chances and proposed it to Spyderco R&D to have a closer look at a modern Piemontais Design (handmade in the Vaucluse) :cool: .
Perharps it will turn into another collaboration. I don't know.
But for your information I made my homework for that ! Friction folders rules ! :D

cheers

Scott,

The friction of one's hand keeps a friction folder open. Think of the Spyderfly as sort of a friction folder. A slipjoint requires one to slip the blade out of joint from the backspring to open or close the blade.

I wish you great success in convincing Spyderco to make a friction folder.

So basically the knife utilizes your hand as a locking system? I thought it was just the friction of the pivot that held the knife, but if most of them have that appendage on the blade for the hand to block, than it sounds like a pretty good idea.

Thanks for the explanation. :cool:

My first question would be, how are these normally carried? I would think the projection (by the way, what is that called?) that serves as both an opening device and lock would make normal pocket carry impractical. It would also rule out tip down clipped carry, and tip up would seem extremely risky. A sheath / holster of some kind would appear to be the only practical carry method.

Unlike Opinels and Laguioles, which have a certain fluid grace to them, but aside from the wood handled one which has a certain primitive charm, I don't find anything the least bit appealing about these.

Thanks, but no thanks. Not my cup of tea, sorry.

I like this idea. I'd buy one if I liked they shape of the knife otherwise. I believe Joe Pardue makes something like this called the toggle folder.

:spyder: So a typical straight razor would be considered a friction folder. I must be missing the appeal. :confused: :spyder:

The main purpose of this is to be legal in most european countries. That would be nice. We all carry illegal stuff here (even the Ladybug...), and we are subject to lose our Spydies if searched by a suspicious cop...

BTW, don't forget the corkscrew, this time!
