yeah bear claws are sharp, camping one time, deep adirondacks, ranger comes around and tells everyone to tie off packs, high up , girls in next lean-to do not listen, i guess they figure the ranger was exagerating, wake up to them screaming as the bear climbs around on the roof, next morning we find their packs half a mile down opalescent brook, sliced wide open as clean as a razor cut, not a frayed edge to be seen, so those are mighty sharp claws on all bears
