That's gotta be one pretty big hammer considering that Ruby goes around swinging a scythe that's probably over half her weight and handles it like it's made of paper. Extrapolating from those same RWBY physics that thing looks<del>glorious</del>hilarious in my head. It's gonna allow for some really cool team combos though. Lionel could probably boost both of his little faunus teammates flying to cloud level with it.
