There's really only 3 knife shops in Manhattan with any sort of selection. The best is probably Iceberg Army & Navy on Broadway about 2-1/2 blocks north of Canal street. Very high prices though. Paragon Sports on Broadway and 17th street is pretty good, though their selection has become less than what it once was. Though probably not true, it SEEMS as if they don't restock the knives that they sell, so slowly there are less and less knives in their selection. They're also the only store in the city I know of that sells custom knives. Prices are comparable to standard retail I guess. The last place is a martial arts store on 6th Ave and about 28th or 29th street, Goodwin or something that has "good" in it. More than half the selection are cheap Chinese/Taiwanese ripoffs though. High prices on the brand names too.
