With its two different tooth patterns, the Ryoba saw ensures optimum cutting performance not only across but also along the grain, making it the most versatile saw for carpentry and joinery.


Blade length is 240mm with 23 teeth/30mm and 0.45mm thickness.

Blade Thickness: 0.45mm

Kerf: 0.73mm

Handle type: Magnolia wood wrapped with rattan offers a comfortable grip



The Ryoba's thicker saw blade allows backless control and thus cuts of any depth flush to the surface. Gyokucho use a method called impulse hardening to increase the durability of the tooth tips.

The cutting edge is heated for 0.003~0.005 seconds by applying an electrical current, instantly hardening the surface of the steel while maintaining the flexibility inside. As a result, the saw’s wear resistance increases. The hardened saw tooth is much harder than sharpening files so the blade cannot be sharpened and needs to be replaced once it is dull.



Gyokucho invented the first replaceable blade Japanese saw back in the 1970’s, and still lead the industry in terms of quality and innovation.

The blades receive a special surface treatment called electroless nickel plating. The plating produces a very smooth surface that resists corrosion and the adhesion of tree resins as well as providing a reflective surface that can be used to accurately align the cut. 

The teeth of Gyokucho saws are hardened by a highly developed version of impulse hardening – only the very tip of the tooth is exposed to exactly 27.12MHz for between 3 and 5 milliseconds, the resulting shockwave case hardens the outside of the tip of the tooth to well over RC67 (harder than a file) while leaving the interior soft for maximum strength. 

With careful daily use in a professional workshop, we would typically expect a Gyokucho saw blade to last between 5 and 7 years.



Japan is the eleventh most populous country in the world, as well as one of the most densely populated and urbanized. About three-fourths of the country's terrain is mountainous, concentrating its population of 125.5 million on narrow coastal plains. Japan is divided into 47 administrative prefectures and eight traditional regions. The Greater Tokyo Area is the most populous metropolitan area in the world, with more than 37.4 million residents.
