Not a Buck guy so let me know if I'm off. 2012 date code. What's the significance of 3 brass and 1 steel pin? Been in a drawer for some time so you can see some marks but blade is unsharpened and unused. Locks up tight with no play and unlocks with no hassle. No sheath $45 TYD PPFF. Trades considered, no real requests but I've been looking at French cutlery lately.
