Butterfly knife skills are a great way to improve one's focus, attention and coordination, plus they look super cool. This Karambit Butterfly Trainer Knife is an excellent tool for learning beginner tricks and flips. It features a dull and harmless, 5Cr13Mov stainless steel blade connected to a 15 cm, stainless steel handle through a sandwich construction. The skeleton design of the blade helps reduce the overall weight, resulting in better balance and control, which is very convenient for beginners. It comes with a locking latch to keep the butterfly secure when stored in a pocket or not in use.
