"Posterity, you will never know how much it cost the present generation to preserve your
freedom. I hope you will make good use of it. If you do not, I shall repent in heaven that ever I
took half the pains to preserve it."
Just picked up a Spyderco folder, no identifying model anywhere on it, but a symbol like an S resting against a pyramid on the blade. Typical shape 3.5 in CPM S30V blade with hole, G10 handles with steel liners. About 5 inches closed. BUT it has a liner lock on the BACK (spine) of the knife. Never saw that before but locks rock solid. Any help in what I have?
