u want a quality knife like that, one made in the USA with the same look but that actually has some collector value?
Check out a Buck 184, the Buckmaster. For a couple more bucks (depending on the auction, no longer make em) you can get ya a sweet knife that will hold its value better, maybe even increase. You'll get a much better quality knife, a very nice sheath, and you can use it as a grappling hook for climbing if the need ever arises (hence the spikes on the guard, which can screw off if you prefer not to have them, as i would do). They came in various finishes, some being rarer than others and costing much more.
knives like the rambo knives got me interested in collecting, then I saw all the other things that are out there. I've heard good and bad things about the rambo knives, good from the tacticool collectors, not much good from broad spectrum and quality collectors. I can't speak on behalf of the rambo as I haven't held one, but I have had the chance at a 184, and the 184 totally rocks
price: ive seen the rambo's for between 60 - 130. 72 on amazon for the first blood currently.
there is a buckmaster on ebay buy it now for 199, all silver version. prices vary with the auctions.
