Familiarity: I've put it through the wringer
I've been using this hammer for hand drilling anchor bolts, as well as cleaning choosy routes. It's light weight but packs a punch, and has yet to show any signs of wear.
It makes sandstone feel like butter... a giant wall of butter that you're throwing fat bolts into.
