You often get the plastic sporks (spoon with fork tines) in fast food restaurants. I’ve read that prisons use them a lot because it is hard to make it into a weapon.
I just read this weekend that Ka-Bar is coming out with a Tactical Spork. It has a handle based upon their Bowie-style Ka-Bar knife. Moreover, unlike your other sporks, this one has a serrated knife hidden in the handle.
I guess there is nothing that can’t be sold if it has the word “tactical” in its name. That said, if Ka-Bar has one at their booth at the NRA Annual Meeting, I’ll probably buy a couple since their MSRP is only $6.93.
