Hmm... Are you by any chance meant to say "blunt" damage? If you are using a translation website it might have got lost in the translation. If what you mean is "blunt" damage; clubs, maces, blunt arrows, staves (staff for singular), throwing rocks and stones, grainflail and small flails, although flails are not used that much in fighting, are great for blunt damage attacks.
You can also choose to attack with the (B)lunt option of any weapon, but don't expect a tiny knife to do much blunt damage. I hope I could help.
