The best pure carbon steel plane.

Special limited edition made only for my father. The BEST of the BEST pure carbon steel blade. This model is not retailed even in Japan.

VAR = Vacuum Arc Remelting. VAR WS#1 is called White Steel Super, the purer version of regular WS#1. Funahiro's Genjyu model sold in Japan uses this steel. He calls it Shin-Wakou (New Tamahagane). It's the closest Japanese steel to Tamahagane, and in many smiths' (such as Kiyohisa-san) opinion, even better than the Tamahagane.

All Yokoyama plane blades are forged using pine charcoal. Charcoal smithing is the best because the low heat prevent the carbon evaporation. But at the same time it is the most expensive method as well, so not many blacksmiths forge this way. Some blacksmiths claims their planes are charcoal smithed but in reality gas forge smithed.
