I'm starting to see light at the end of my shop redo tunnel, so I'm ordering some parts for folders. I've got 2 original designs that I'm going to do next and one is more of a general use pocket knife with bearings that the average Joe would carry. The other, is a beefier hard use knife with washers that could stand up to some serious field work. At least that that's the plan I was thinking about using the Beta Titanium screws from Alpha based on the claims of toughness. Supposed to be way better than regular Ti screws. But, they only have them in 2-56 size. Also, pivot size, does it really make much difference? So here's some questions. Would you use 2-56 Ti screws in a hard use framelock? I'm sure they're great for my general use design, but the hard use? Or, should I look for Ti 4-40's? Would it be easier to find a counterbore bit for the 4-40 screws possibly? The first folder I made I couldn't find a counterbore for 2-56 as best as I remember. Would it make a framelock significantly tougher to have a 0.25" pivot over a 0.125" or 0.187"? Pretty much, you guys that make hard use framelocks, what hardware do you recommend?
