By this I mean can't you just keep replacing the liner over and over when it wears to the other side? Would there be a difference between a titanium liner and a stainless steel liner in regards to wear on the tang of the blade? I guess I have the same question about a titanium frame locks too. I've worn out a few Spyderco lock backs that could not be repaired, they would not lock up anymore(after years of hard use.) I know Emerson will put in a new liner for like $10 and I am sure the other big makers will too so that seems like a great deal to have a knife that you can fix over and over vs. other types of locks? Thanks for you info and opinions....and Happy New Year.
