I really enjoy throwing knives.
Do you?
Would you buy a CPK throwing knife?
Probably not. Throwing knives is a fun pastime, and balance is obviously a very important factor if a line is to be developed. But demand and material pricing pressures have in the past been obstacles that were difficult to overcome moreso than balance, at least from some of the history of throwing knives as I understand it.
There's a very good reason for most knife designs to exist, the CPK line being an example: purpose driven design. Throwing knives serve very little real purpose for the vast majority of knife buyers, I would imagine. Yes, there's a knife throwing competition, and maybe a short-lived CPK fan demand base, but I personally can't imagine trying to shave the costs to build a knife, probably adequately priced at $90, where there's not much return for the maker. And (again IMHO) at best, a tenuous buyer base not driven by a perceived need for the product, a throwing knife. Gotta admit, though, CPK has come out with some kool kutters, where demand seems to always outpace production. The reverse might be true with a thrower.
Something like a chopper can be a fun knife, but choppers evolved to chop materials needed to survive - though they do occasionally cut rope, bamboo, etc, in contests and demonstrations. And throwing knives? They most likely evolved from the need to kill, and you don't see too many ninjas and assassins on the streets these days taking life, ergo probably a lack of need other than for minor competition? '
I am probably a mile off on this one, so do feel free to flail me over the head, but if I had to bet on an enterprise being able to make much of anything on throwing knives, I would bet zed..
