The new chop is equipped with the KICK STOP hidden flippers designed by LEE Williams. This is a perfect match. The design style of Japanese tanto knives is pure. Simply put, it is to remove the extra design. Therefore, most of our Japanese style blades are front-opening, and front-opening folding knives may not be so popular. Flippers are more acceptable and easier to use! But the protruding flippers are always not so Japanese style. Now we have found the final solution to the problem, which is KICK STOP. This hidden opening design is the best partner for our tanto knives. After opening, the flippers are hidden in the handle, which does not destroy the beauty of the tanto blade at all. It is definitely worth your try this new tanto design.
