Review: The look and feel of a real butterfly knife with no risk of severed fingers. - This is a trainer with blunt blades so no chance of cutting off your fingers. It's easy to handle, flips open cleanly and smoothly. The latch to hold it closed when not in use is a vital feature. The patriotic pattern is great, if you're proud to be an American!
Review: Fun - Purchased for my son at his request. He loves it and uses it almost like a fidget toy. He enjoys practicing different moves and I don’t have to worry about him hurting myself. It’s also pretty well made and has shown no signs of deteriorating.
