One Piece Japanese Anime Tanto Sword - 21 Inch Carbon Steel Replica Short Katana All Black & Gold

The blade is sharpened to 45% which is not good for cutting or any Japanese swords. To achieve that - blade must be sharpened to 25% as dagger blade so in the future you would just polish the blade instead of sharpening it.- Pic 1 shows blade after flipping with the sword instead of a hand, so it can handle the pressure of 90-100 kg easily.- Pic 2 shows that to make 25% dagger angle blade - sharpening will reach the hamon level (battle swords already have that angle).- Pic 3 shows that even after pressure and sharpening - the blade is still straight and so sharp that don't deflect light anywhere (description of dull or 45% blade)
