I am wanting to make a set of titanium liners and then multiple different scales for a balisong blade that I have. I don't have the original handles for it. I'm not sure how thick the titanium liners need to be for it to be structurally sound. I'll be using grade 5 ti for the liners and I will be making the scales out of .125" micarta. Any suggestions on how thick the liners need to be?
