actually this would be really interesting as a weapon
like the skeet thrower is a handheld rifle that fires a projectile about 2/3rds to one half the size of a blockhead that's launched side-on through the air like a big sawblade, and getting hit by the skeet causes lots of damage but shooting the skeet causes it to explode
alternately you could replace the skeet with a really big slow-moving rocket or something, but the concept still stands
