FingerArmor2 reduces your risk of injuring your fingers while using knives. Put your index, middle and ring fingers into the finger pockets, and enjoy convenient cutting/slicing with low risks. This tool is designed for the left hand (right handed users only). Four sizes available (width of each finger pocket): S: 16.79mm M: 20.21mm L: 23.72mm XL: 25.26mm FingerArmer2 is based on the FingerArmor beta. (http://www.thingiverse.com/thing:668875) It now comes with a sleeker look, better grip and even more protection. This design DOES NOT GUARANTEE a risk-free cutting. Please stay alert when using knives. Based on the feedback we receive about FingerArmor. we redesign the shape to provide better protection and add more grip at the bottom. The new design should be able to print in a better finish as well.
