Gyokucho is the independent sales office for Razorsaw Manufacturing. Razorsaw Manufacturing was founded in 1969 in Hyogo, Japan, with a focus on producing handsaws with replaceable blades. They incorporated Gyokucho six years later to sell and market Razorsaws and other products under their umbrella.

Gyokucho produces a number of cutting tools, including pruning shears and utility knives, but the replaceable-blade Japanese pull saws produced under the Razorsaw brand remain their most popular.
