Re: Don't know if knives can be considered part of this...
Basically; I think I'd rather have a single shot, even in .410 shotshell, than a repeating set of .22's.
And the way they had to replace the handle to "reload" the CO2 knife... if these guys are serious and want to charge over $300, they need an actual reloading system. Shouldn't be too tough for them to make a catch that lets someone reload that thing as fast as a pistol. Also, a second trigger on the butt would be smart, to allow a reverse grip, or to allow a knife stuck in something but not triggered yet to be set off easier.
