Our Bamboo Froe is designed for splitting-out the bamboo pins used to fasten together Japanese joinery. You will find it equally useful for splitting wooden pins used in all fine joinery work. The blade is a hand forged triple lamination of high-carbon white steel and soft low-carbon steel. The Master Blacksmith Ikeuchi individually tempers each blade to ensure a long edge life during demanding use. The blade is 1/8˝ thick and sharpened with a double bevel. The edge length is 6¾;˝, and the overall length is 12¾˝.
