Attended my first blade show today(Oak Lawn,IL AECA)and purchased a Buck 881 Mini Strider Spear Point with BG-42 blade steel. I have a couple of questions about the blade marks. At the base of the choil it is marked SB.2 and directly underneath is the symbol for 2001,on the other side of the blade it is marked BOS BG-42 U.S.A. An interpretation of the marks would quiet my curiosity. Also the pocket clip is super tight is that normal, or is there a way to loosen it? I must say the knife is truly sensational. My knife knowledge has sure increased the past couple months reading this forum...Thanx and keep up the good work.
