Rattan Wrapped Handle
A classic wooden handle wrapped in natural rattan. It is light, offers good grip, and has a traditional look and feel that many woodworkers prefer.
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.
Straight Handle
A simple, straight handle that lets you fine‑tune control by moving your hand closer to or farther from the blade. Closer gives more precision, farther gives more power.
Replaceable Blade System
The blade can be removed and replaced when dull or damaged, usually via a simple screw or click‑in mechanism. This lets you keep the same handle while swapping blades for different tasks or renewed sharpness.
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.
