GREAT FOR TOP OF KEY WAY PICKING The Peterson Pry Bar is for the many locksmiths who requested a strong and solid tension tool for applying "top of the key way" tension. At 0.050," our Serrated Pry Bar is the width of the key blade segment of most key ways. This strong-arm partner is notched to eliminate contact with the first pin, flat to fit in your pick set, and has our serrated edge technology that locks it in any key way! Made of Peterson's famous Government Stainless Steel.
