Impulse-Hardening
The teeth are hardened with a quick, high‑frequency heat treatment so they stay sharp up to three times longer than normal teeth. These blades cut very fast and clean but generally cannot be resharpened and are replaced when dull.
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.
Hijirime
A special tooth pattern where some teeth are slightly shorter than others so they don’t cut but act as tiny cleaners. This staggered height helps clear sawdust from the kerf, reduces cutting resistance, and improves overall cutting quality, especially for fine crosscuts and rip cuts.
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.
