Pro-Tech's newest design in the Runt series, the J4, now comes in a tanto blade. This limited edition model, the 5452, has a stunning black 6061 aluminum handle with ivory micarta inlays. This gives it the unique "Tuxedo" look that is so popular. The tanto point blade is double ground and has a DLC black finish. One of the best Cali-legal series of automatic knives on the market, the Runt J4 is perhaps the most popular of all. As with every ProTech knife, the finish is top quality and the action on the spring is fast. If you are looking for a fantastic every day carry auto knife or a knife for your collection, the 5451 will do the job nicely.
