 It is similar to, but not the same as, some early Japanese swords that had "kamasu kissaki" ("barracuda tip"), a "nearly" straight edge at the tip whereas the typical "tanto point" as found in the west has a straight edge.The barracuda tip sword was sharp but also fragile whereas modern tanto point are often advertised as being stronger at the tip for having nearly the whole thickness of the blade present until quite close to the end of the knife.Knife tests have shown that penetration ability of this style of blade is comparatively poor but it is possible, if the tip is strong, that more force can be applied allowing greater penetration without damaging the tip.
