Yokoyama-san's plane made with Tougou-kou (very close modern replica of Tougou Reigou steel).

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.

It comes in a specially ordered 4 sun 5 bu box, signed and stamped (stamped upon request). Dad's calligraphy on Kiri box. I think he did a great job this time!!!

Osae is made by Yokoyama-san himself. Checkout the rough Urasuki, it is definitely not by Uchihashi-san. Uchihashi-san's job is neater(^^). I've never seen an osae made by Yokoyama-san before.
