Towcutter: If you read the thread, you'll find the liner thicknesses that top folder makers consider minimum, adequate, and reasons why thicker liners have advantages. I don't consider wear a reason to use a thicker liner, since wear doesn't really come into play if the locking geometry is correct. The benefits of the thicker liner lie in increased buckling strength and resistance to deflection.

Thin Liners ??

What about the depth of cut in the liner for the lock bar in relation to the finished angle on the blade tang and the lock bar mating surface?

I was in Germany a couple of years ago at a knife factory and the owner showed me a folder with about a 3 1/4" to 3 1/2" blade. I asked him what liner thickness he was using and he replied 1mm (.040). When he wasn't looking I started beating the back of the blade on the table. I was surprised that the lock did not fail.
Several reason why this was such a stout liner lock: #1: It was made out of stainless steel. #2: it was short and very wide. It must have been well over 3/8" pushing close to 1/2" and about 1 1/2" to 1 3/4" long.
But you know, the first impression was "what a small liner for such a big knife". I guess you can never judge a book by its cover!
Stumpy, if you change one thing, it affects the others. I don't know if this answers your question. Remember that a liner lock works off of a radius (movement is a radius), while other locking mechanism are straight plunge. Straight plunge locks would be for example, a bolt lock, an axis lock, a button lock and even E-Lock (it might rotate but it locks straight). Straight plunge locks are easier to calculate angles, depth, movement, lock-up, etc... when you talk about an arc, things are constantly changing from one degree to another.

Yes,thanks Allen.You answerd the question.The configurations are almost endless with respect to angle,liner length,thickness,material ect.I guess it's just up to the individual maker to find what works best for him and his customers.I do know why I stick just to collecting though.
