ABOUT GYOKUCHO RAZORSAW
GYOKUCHO RAZORSAW brings together Japanese saw-making expertise and practical replaceable-blade design. Its roots lie in Miki, Hyogo, a town with a long metalworking tradition, where saw craftsman Masaaki Tomosada established Razorsaw Manufacturing in 1969.
The brand places quality at the heart of its work, carefully producing each blade under strict quality control. Its in-house-developed impact-hardening equipment treats blades individually to create hard, durable cutting teeth while retaining the flexibility needed in the blade. For users, replaceable blades mean a fresh cutting edge without replacing the complete saw.
