What's a good size and brand. Looks like a good/fun skill to learn. Checked out Smokey Mountain web site and alot to choose from.  Hey, how about knife throwing instead of darts at the bar. Just kidding.

I used to throw my knives around, never did anything but banged them around

No but am dead on with a 16d nail.

Stay away from knives made fron stainless, they will break. I use the large (15") Pakistani bowies. I knock the handle slabs and guard off and dull the edge on the grinder. It's easier the throw a larger knife than a smaller one. You don't have to throw as hard to "stick" it and there a larger arc where the point will stick.

I use a target I made from scrap 4x4 clamped together with pipe clamps. This set up allows me to move and turn sections as they get chewed up.
