* HHB trainers are an exact replica of the live blade but with a couple of small but important changes.
* The anodized blue color is a safety standard in Military training. All inert training devices are blue. (blue guns, blue training knives, blue Claymores, etc.)
* The tip of the each trainer is 0.5 inches shorter than the real blade. When you practice with a trainer, you touch your target with the tip but cannot enter the target. This shorter design builds an automatic half inch penetration into your targeting and negates the training scar created by using trainers.
