Yeah, if they could just include Ricin it would be the "perfect weapon." I can just imagine some idiot trying how to explain to a jury how he used the Waspknife in self defense. "Well, he came at me, and I stabbed him to protect myself. Then I pushed that little button, his insides froze, and then he exploded all over me." I just don't see anything but trouble coming from this contraption, and it is most likely to affect lawful knife owners.
