A local guy wants to trade six NIB S&W knives that he claims were designed by Blackie Collins for a slightly used Remington 870 12 gauge with 3 choke tubes and 100 rounds of ammo. He has 3 each of 2 styles, a "survival" knife with a hollow handle and a "skinning" knife.

Dones anybody here have any hands-on knowledge of these knives and if they are worth more, or less, than his $100 asking price? I have around $400 in the shotgun and ammo.
