The Dirty is the Rat's big brother. It's full size grip is strong, sturdy and designed for someone who wants a little more in their hand than the Rat provides. However, like the Rat, The Dirty is easily carried and concealed, providing comfort and reliability in one package. This single edged blade offers a great mix of full sized use and ease of carry. The Blade At the five inches long this blade can easily reach all the vital targets of the body. Most from multiple angles. The width is just over one inch wide providing a wide wound channel and great leverage. Single edge is legal in most places and the false edge on top provides the all important point geometry necessary for ease of penetration through tough clothing or other materials. The Handle A strong wide grip provides safety and security to the user. The deep finger notch and the curved palm assist handle makes thrusting more secure and reduces the chances of riding the blade. The hook on the end of the handle provide a mechanical advantage when performing the drawstroke, making it faster and more secure. It also puts the blade in the Master grip, giving you the same grip from the draw, every time. The Trainer The trainer is an exact replica of the live blade but with a couple of small but important changes. The tip of the Dirty 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. The anodized blue color is a safety standard in Military training. All inert training devices are blue. (blue guns, blue Claymores, etc.) The Sheath Sheaths are custom Kydex with a proprietary clip designed by Head Hunter Blades and fit both the Live Blade and the Training Blade. Simply take the live blade from your sheath, place it in a safe location, put the trainer in the sheath, and you are ready to train! When you are done, reverse the process. HeadHunter Blades uses small rivets to ensure a small and lightweight sheath, spring clips with a garment hook to ensure a positive lock onto garments, and expertly molded Kydex. Comes with original box and papers. Excellent condition.
