The blade is made of handforged and folded High Carbon 1095 steel. The gunome hamon is evident and prominent and the grain pattern (hada) shows distinct layers.
The Koi Katana is forged, folded and differential hardened. The nagasa or blade is made of High Carbon 1095 steel. This steel is homogeneous and has a perfect Carbon proportion. Because of this High Carbon percentage the blades are very strong and made for functional use. It show a geometric chu kissaki.
The steel undergoes the most complex treatment and is handforged. Because we want to exclude bubbles in the steel from the blast furnace and to make the steel even more homogeneous and make it more aesthetic the steel is also folded 8 - 12 times. This causes a very nice organic hada (aka grain) with an esthetic and traditional atmosphere.
Of course all the blade are traditional clay tempered and the created Guome Hamon is appearing due to a machine (foundation) and hand polishing.
The blade has no Bo-Hi and this causes a massive nagasa and this will create more power while hitting a target. Also the blade will experience less resistance while hitting some tatami and the cuts will look cleaner using a correct technique.
The Tsuka is covered with white same (rayskin) and wrapped with Japanese Cotton. The Tsuka is covered with two Mekugi (Bamboo Pins). The Kashira and Fuchi are made of blackenend iron.
The Koi Tsuba is made of blackened iron.
The excellent black saya is wrapped with nice black Japanese Silk sageo.
