Introducing the 99 Necron™ Trainer, a high-performance butterfly knife trainer designed to perfectly mimic the feel of the 99 Necron™ Bali-Song®. Available in Blue G10, the Necron™ Trainer is optimized for expert flippers with latchless G10 handles and a skeletonized 440C training blade. Fine tune the Necron™’s balance and speed with adjustable tungsten weights and extendable handles for your perfect flip and desired feel. Like it's live-blade counterparts, the Necron™ is finished off with a hollow diamond texture found on the safe handle to give the user a tactile indication of which handle to grasp to avoid a sharp bite
