Odachi or nodachi was a type of traditionally made Japanese sword used by the samurai class of feudal Japan. Odachi are difficult to produce because their length makes traditional heat treatment more complicated: The longer a blade is, the more difficult (and expensive) it is to heat the whole blade to a homogeneous temperature, both for annealing and to reach the hardening temperature. The quenching process then needs a bigger quenching medium because uneven quenching might lead to warping the blade.  

The blade is forged from 1095 high carbon steel and clay tempered, both folding grains and hamon are clearly visible. The sword is well-balanced, it's battle ready.
