Oso Grande's collection of Practical Katanas gives the martial artist the opportunity to own and use a battle-ready sword at the cost of an economy sword. The blades are forged and differentially tempered, using the same process as more expensive blades and producing an HRC60 edge and HRC40 back. The temper line is authentic and prominent. Cost savings are effected by using fittings which, while making no claims to authenticity, are very strongly built to withstand the rigors of cutting exercises in the dojo. See also the Practical Wakizashi and Practical tanto for companions to this sword.
