SUGOWAZA 420 Spare Blade

Sharpenable Blade

The teeth can be sharpened with a file when they become dull. This allows you to keep the same saw in service for many years and is a good choice if you prefer maintaining tools rather than replacing blades.

Mirai-Me (4 Cutting Angles)

A special tooth design with four cutting angles that lets one saw handle rip cuts, crosscuts, and slant cuts. It leaves an exceptionally smooth surface that often needs little or no sanding.

Electroless Nickel Plating

A thin but extremely durable nickel coating that covers the entire blade, including the teeth. It greatly improves wear resistance, slows rust, and helps prevent sap from sticking, so cuts stay smooth and easy.

Non-Set Teeth

The teeth sit within the blade’s thickness instead of being bent outward like many Western saws. Combined with a taper ground blade, this gives very smooth, fast cuts with minimal waste and a very clean surface.

Progressive Teeth

Tooth size changes along the blade, usually starting finer near the handle and coarser toward the tip. This makes starting the cut easier and then speeds up cutting once the blade is fully engaged.

Curved Blade Design

A gently curved blade that helps keep more teeth in contact with the wood as you cut. This improves cutting efficiency, especially in pruning, and can reduce strain on your wrist and arm.
