The M4000 High Yield Lock Pick Set consists of fifteen picks with moulded handles, two double ended picks, eleven tension tools, and an oversized zipper case made of the finest Valentino leather. Specifications for the M4000 include the fact that each high quality stainless steel lock pick is .031" in thickness. The high yeild steel used in this line of fine lock pick sets is much harder than typical stainless, having a minimum tensile strength of 270,000 PSI, compared to 185,000 PSI for Full Hard. What does this mean? It solves one of the problems with lower quality stainless steel lock picks in that it resists breakage.
