Thanks for your reply , My knife was verey hard use tool in a very harsh environment , the mekong delta. It was wet most all of the time so you know what that means , the blade acquired a brownish and slightly pitted condition but the edge wae kept very sharp for obvious reasons. The sheath suffered some also as I had no conditioner for it. I changed out the original stone in the sheath pocket { if it came with one, i don't remember now } and put the fine stone from a buck honing kit that my father sent me . I made a sort of frog for the sheath that would snap on to my web gear pistol belt and there she rode for my tour, I dug with her, cut wire wraping on c -rations and steel bands plus canvas webbing,etc,etc. never had to use her in combat thank god but always felt good having her by my side night and day yes the sheath is the rivited one with lashing holes in the belt loop and a tie down tab with two holes at the tip of the sheath. she now resides in the safe and reminds me of along time ago in the "land of winkin an blinkin an nod" mjmcdowell
