Rocky,
There is nothing to forgive. If I remember this knife from before it is a vague memory. (Something that occurs more and more these days) I think your Father picked it up, second-hand? If so, who knows (or wll ever know) the exact origin of this blade. It sure has way-cool old micarta and spacers...and it's a "keeper" in your eyes. That's all that really matters.
One thing a lot of folks do not know (and I am just reminding myslf of) is this: Gary Randall's first "job", when he started making knives for Bo, was cutting thumb notches! That little bit of trivia gives this thread some legs!
Best, Capt. Chris
