The "Scout Safe" is intended for younger scouts. It features a prominent guard combined with a flared pommel to help smaller hands keep a firm grip. The blade has a blunted tip, and the handle circumference is also sized to accommodate smaller hands. It's up to you to decide if your child is experienced enough for a knife like this though, as the blade is still very, very sharp. The flat-style sheath has a loop and snap fastener to keep it in place.
Below are the detailed measurements of this knife. One important note: for best comfort and grip, the length of your middle finger should be similar to the circumference of the handle.
