In 1969 the company marketing the RAZORSAW brand invented the system with the thinnest blade ever for the most efficient cutting.

The introduction of this new disposable saw amazed the Japanese woodworking industry and its success has proved that this method of manufacturing Japanese saws has taken the world by storm.

Each blade is impulse hardened. Impulse hardening is a new technique of heating for 1/1000 second by impulse energy at an extra high frequency resultingin hard and tenacious steel that gives remarkable durability. Once you have used a RAZORSAW you will wonder how anything else in the workshop did the job.
