Been using similar par of Rongeurs that My father used in the 70's and they are my "GO TO" for root tips, bone snips, aggressive sub-boney broken teeth and tissue removal. Bent the tips of the old one a few years back and could not find a replacement Rongeur until I found Blumenthal sold by Deutschedt. Hands down a must in the Dental Armamentarium for aggressive Oral surgery.
