With a blade length of 5.2 cm, the Boker Plus Tech Tool Mini is much more versatile, practical and effective than many other key chain knives. However, it's still small enough to add to a keychain without a problem. The Tech Tool Mini has all the premium features of its big brother: a polished, hollow blade made from Sandvik 12C27, contoured G10 black handle scales, and a bolt-on handle. A fixed loop and key ring are part of the Tech Tool Mini's standard equipment. It also has a multifunctional blade with screwdriver, strap cutter and bottle opener.
