Below is my Lockpick kit, It is made from high carbon steel that has been spring tempered and then hot blued. The dimensions are 3.5"x2.25" and are .035 thick. These were designed to fit in the credit card slot of your wallet or in the lid of an altoids tin if you decide to make a Altoids tin survival kit. I when active always had one under the liners of both boots for E&E situations. This lockpick kit retails for $30.00
