You would be much better off with a real, purpose-designed thrower. They are not generally sharpened, so you can practice blade and handle throws, and what handles there are (if you choose a model with a handle at all) is usually something simple like riveted leather that won't be damaged by a non-point hit. They are usually made of a type of steel that is shock resistant, like some type of spring steel, so they won't snap if they hit wrong. They are, as well, balanced for proper throwing. You would do well to buy three or so, so you can practice to get your releases and spins consistent from throw to throw, without having to walk up after each throw. Now, I have a trio that I picked up at a show out here, and they were sold by the guy putting on a throwing exposition at the show. They are from Bob Karp, I believe. Sixty or seventy bucks for the set, and they look like they'll keep going forever unless you use big boulders as a backstop.
