Hello there. I've been using a forge for a few years now just making little things. Like a metal frame battery holder for my father in laws trailer. Coat hooks and just other things. So I've got an upgrade idea for the lock back folding knives. It sounds good in theory but will see once its made. Ive only made 2 knives this hole time out of 5160. And after reading and talking with a few others, the few plates of CPM 154 won't do me any good without a heat treating oven. So I'm going to stick with the 5160 for know an see how they come out. I have a few questions about the frame of the knives. I don't really want to make the hole thing out of 5160. I think some titanium or some cheep 420 will work better. But how thick would be a good place to start on the frame. And on one of these I'd like to place a secondary lock. Kinda like the axis lock on benchmade. but more it pushes forward and locks the blade in place and pull back to be able to release the blade so using the normal lock it will release. I seen some secondary locks on a few knives amf just want to try it out. this one is mine its a tester and this one is going to be the karambit. EDC knife. It'll be first so I can learn from my mistakes when making the others for christmas. I've looked all over and found the design Iike. Sorry that I'm coping someone's design. They say imitation is the sincerest form of flattery. So im taking a straight blade design an making a folder out of it. Anyways. Anyone know how big the inside of a karambit ring is normally. I've read 1 inch but would like to ask to make sure. I've got medium hands. Also I've found knife makers supply. And usa Knife maker. Im looking at the handle materials. I want something thats got a nice grip but wont freeze your hands like steel in the winter does. So I'm looking at micarta or G10. ive read that micarta is really grippy but can be a bit soft. Easy to dent and chip if not made well. And G10 is just stronger but not as grippy. Anyone with some experience on these. If you could weight in and just tell me what your preference is and why. These are my first folding knifes so I dont expect them to be shining art. But I do want them to be decent and good so they want to use them. Anyway thanks
