Round tins are the industry standard, You could also try the less popular square tins, I'd avoid the triangular tins altogether, they are a bit too pointy...... /sarc
Bend the sharp edges back in on themselves and you shouldn't have a problem. Or make crusts that don't need a tin.
I've always wondered how well paper food trays (the kind used at concession stands) would do as stand-ins for pie tins. The chance of hurting yourself would surely be less.
I've always been concerned when I've seen the pie tins with the jagged edges just sticking up. That's a quick recipe for cuts!
Just fold the edges back underneath the outside edge of the tin, then they're completely gone. I've used lots of those and never had any cuts.
Regarding Don't_Panic's idea of the "paper" food trays: First of all, they aren't really "paper" as you would think of it. They're thin, but stiff cardboard. Those edges, again pointing right at the person being pied, could give paper cuts, or just plain hurt. I don't think they would do a good job. If they were much flatter, they could work.
Actually, if you use a plain old paper plate, maybe one with a little raised edge around the outside, and just sit your pie crust on it, it would work, and then just fall away.
Absolutely right! Instead of throwing tins, get twice as many crusts, and bake two of them into each other. It'll mean a fair amount of cooking time for a lot of pie crusts, but you should then be able to throw them by holding the crusts, which will safely shatter on impact. That's what Keaton, the Three Stooges, and Laurel and Hardy used, so you know it's the best way to go.
Obviously, crumb and cracker crusts don't work too well for this.

This is what I do for the pies I hit my wife with, but you still have to be careful as some sharp areas can be formed by the folding-in process. I don't throw them either(at her request), so that would be another way cuts could easily happen even with a modified tin.
