This Carbon Spring Steel DCAP Diamond has an Electroless Nickel Plating applied before it is molded into its strong fiber filled nylon handle. The reasoning behind this reduced shank thickness is to overcome the security provided by having deep cuts close to the bow of the key. As locks typically pick from the front to the rear you need to enter the lock deeper. Movements of the thicker part of the pick shank can tend to over drive the front pins. I have discussed this with locksmiths and several have told me that they actually key their own homes with deep cuts, because of the security provided. These 10-95 steel picks are robust, and this light weight plastic handle provides for an agile and responsive picking experience. You will find that the picking feedback is easily felt throughout the handle. While we always recommend our Government Steel Plastic picks (GSP) as an even stronger product, customers will find that these ENP (Electroless Nickle Plastic) based picks allow them to purchase an excellent quality pick on a budget.
