I've just received a Buck Strider 880 which I bought in Ebay. But the knife seems different from what I know. Its closed length is 4 1/16'' and blade 2 7/8. One side of the blade is marked "STRIDER" and "BUCK"; The other side "BOS" next line "BG-42" next line "U.S.A.". I thought it was a Buck Strider Mini, but I learned that the Buck Strider Mini made from BG-42 steel are "1st Product Run", but mine has no such mark. Could anyone tell me the actual name of this knife? Thanks.
