I find it very nice when someone asks for feedbacks on his own design...and of course, I like people designing knives
As you know, people from my land can be very clear and straight in telling things. So here I go.
I do like the shape of the handle and the blade, and the handle/blade proportion. I assume the grind on the blade is flat, which I would prefer, but maybe you it's not.
As for friction folders, I have a problem with some of them. Your design helps me bring out the topic, I don't intend to hijack the thread, since your knife has the same feature.
So, as you surely know, all Sardinian folders (the knives I grew up with) are friction folders. I assume it's a matter of habit, and also of quality in the making (the quantity of friction in the opening/closing is a very important variable), but I never saw the need of a backspring in a folder. I guess I'm just used to an "all manual" opening/closing, and even though I own and use different kinds of folders, I still prefer friction folders.
What I don't understand, is those friction folders (like the svord peasant, or your knife) that have the "blade locking element" (in Andi's words) that comes out so much from the handle in the closed position. In my opinion, it's just bulk and extra length, especially in the pocket, and does not offer any advantage. I prefer the handle to have a little cut to pinch and pull, or eventually a nail nick, but not that thing (I have no idea of how to call it). As for opening the blade, it might be comfy but it's unnecessary. As for keeping the blade open, friction and cutting movement always worked fine for me, even without the backspring or that "thing"
which makes a 4" knife as bulky as a 5" one.
It is, of course, a very very personal opinion, and it's not just about your knife...which I do like in all the other features.
Thanks for sharing your design with us.

This is, maybe, an unconfortable building part of friction folders.
