Mirror finished cast brass knuckles by Jay Tee. "Over 100 hours have been spent creating the finest Brass Kunckles available anywhere; 100% American made from start to finish. First, the molten brass was cast into rough knuckles. Then I prepared the piece by grinding flats and smoothing the curves. Due to the variations during casting, every one finished uniquely different. Finally, they are hand finished and mirror polished" Comes with nylon zippered case and COA dated 7-17-17. Has some very tiny scratches, otherwise excellent condition.
