If your arming yourself to place that knife on Egay, than may your balls burn in hell, while the rest of you treads water for ever....just kidding. The BMF is one of those old knives that people either hate or love, I happen to really like them, I own 2. I probubly like them so much, because it was the knife I wanted as a young knife nut, and couldn't afford. The short blade is from the earlier ones, the compass, I can't help you with, but I believe there were 2 different styles. Both mine are clear plastic, rectangular, with the rotating round degree dial, and Silva. The knife could be argued not that great, comparing it to some modern knives out there, but I think, for me, it is a great survival tool. the knife is strong, and comfortable. the sheath is stout and useful, and the thing just looks cool. I know, I know....saw teeth mean the knife sucks ( to some folks) but you know what, I give the knife a 2 big thumbs up. I hope you keep it, and if you want to get rid of it, don't just give it away, there are still a couple crazies like me out there that will give a pretty penny for a good one. Gene
