The Z-Saw Panel Piercing Dozuki is a small Japanese back saw with a 150 mm blade and a hooked tip that starts a cut in the middle of a board or panel. We sell the saw and the replacement blade.
It's made for intricate, precise work, from musical instruments to dovetails, and it's one of our favorite small fine woodworking saws. The hook at the tip of the blade starts piercing cuts where no other saw could, and from there it cuts on the pull stroke like any dozuki. The 0.30 mm blade has 1.41 mm pitch teeth (18 TPI) and cuts a 0.49 mm kerf, and the steel back keeps it straight. Blades change without tools: tap the end of the handle to release the old one.
Z-Saw's maker, Okada Hardware, has made saws in Miki, Japan since 1943 and was the first company in Japan to impulse-harden saw teeth.
