Hi guys

I am in the process of designing my forth folder, and my question is, how thin is too thin for titanium? The first three I am working on are farley thick (.090 on 2 and .125 on the other) I would like to use maybe .050 thick for a EDC type knife but I am worried that it is to thin.

Second question , if I use 440C for liners should it be heat treated to the same Rockwell as if I were making a blade out of it,and should I bother having cryo done on it.

Shouldn't long before I post some pics of my first batch, The blades are at heat treat and once I get them back I want to get them done as quickly as possible.


I like making folders. It's fun



thanks a bunch

The thinnest I make as far as a liner lock is a .040 but that is stainless hardened to about a Rc45. That seems to wear pretty great and although not quite to the hardness of the blade it does keep it from indenting but it is still something you can drill with a normal everyday drill bit. I've even managed to thread Rc45 stainless for a pocket clip after hardening so there is some benefit to keeping it around that level of hardness I think.

As for titanium I think the thinnest I'd go with is a .050. It is plenty strong and many people use that thickness without worry so I'd say go for it on that thickness. I have .068 and .099 titanium that I've been using for my liner locks and I must say I like the thicker ones better but they are harder to cut, and harder to bend. On the ones thicker than .070 I have to do a cut out of the back part of the lock to make it easier to bend. Up to that they seeem to bend fine for me but it is a grit your teeth and pull kind of bend if you get my drift.
 
.050 6al/4v Ti is perfect for a linerlock that has bolsters and scales. There's really no reason to use thicker Ti unless you're building a framelock. :)
