First, let me officially warn you of the dangers of knife throwing: it's
addicting. I gotta tell you, it doesn't stop... pretty soon you wind up picking up just about any object in your hand, and start to analyze its potential to stick. Doors and sections of drywall in your home may develop strange holes blown inward and out the back. Screwdrivers and other tools disappear for weeks at a time....
Assuming you're ready for that
)), you need to get some knives. Others may argue here, but you shouldn't begin expensively here.
Start with low cost throwers! You stand a very good chance of losing them or damaging them badly.
I don't think I've ever spent more than $20 on a thrower. You can get them just about anywhere, too. Or you can make your own out of an old set of kitchen knives ground or filed to a reasonable spear point. As long as they're remotely balanced, you can start learning right away.
I'd spend more time on finding useful and safe throwing targets before worrying about the blade manufacturer.
Once you develop your own throwing style, you'll have a better feel for what type of throwing knives you like and would want: heavier or lighter, longer or shorter, etc.
