In response to the Q of Frost(Taiwan).
Frost(not Frost-sweden) are purveyers of junk. You can't miss 'em. Just look for garish and gaudy "rainbow" pattern pakkawood handles, funky and totally useless "fantasy" shapes, etches of outrageous names which could hurt your case in court in the event that you had to use the thing for self-defense, and worst of all, bright chrome-plated guards which are most likely powdered zinc castings which could prove deadly to the wielder if ever struck by an attackers knife blade. Rumour has it that Frost doesn't bother to heat treat most of their junk blades. Just check out the "tennesee knife mafia's" catalog(Smoky mountain knife works) They are a bunch of conniving rip-off artists who steal designs from knifemakers.
