  1. Master Level Quality!!

    Posted by Evan G. on 17th Oct 2019

    I purchased a set of 577 jaws for my Craftsman 5166 Vise and they are the highest quality vise jaws money can buy! Kevin’s work is top notch! Fitment is perfect, surface finish is impeccable, and the rainbow color from heat treating is very pleasing to the eye! 10/10 would recommend!
