I don't think that would be hard to implement as a secondary gear. It could have a great damage against survivors and hercs, you wouldn't recover them but need to find new ones. It could be interesting to be able to bring more than two by default. The real question is: would we need additional stuff in our inventories that would be useful in a very limited number of cases ? Keep in mind we do not use nades on zeds even with their exploding range, knives would be pointless. Difficult to use in raids because you couldn't throw them from as far as a sniping range. And for hercs, it would be useful only if it could kill them in one throw.
Fancy stuff, but I don't see a real use for them.
