IRWIN 19TPI Japanese Back Saw for Precision Cutting. A professional Japanese saw with a very thin blade and a back, designed for high-precision carpentry, carpentry repair, and model work. Suitable for flush cutting. The tool is used for both hardwoods and soft or thin materials - chipboard, plywood, laminate, plastic, etc. The thin and light blade with a special tooth geometry and a back provides an absolutely clean cut and excellent finish with minimal effort. Induction-hardened teeth stay sharp longer, and the pulling action eliminates jamming and promotes a straight cut. The blade features fine, very sharp 19 TPI teeth for a perfectly clean and even cut. The tool has a button to detach the blade from the handle, which will be a very convenient feature for both transporting the tool and replacing the blade. Blade length - 270 mm. Teeth per inch (TPI) - 19. Steel blade. The comfortable pistol-grip plastic handle does not cause hand fatigue, and the grip area is rubberized. The IRWIN® Jack® range of saws are best-in-class hand saws for modern professionals. Advanced tooth technology and the ergonomic ProTouch™ handle make IRWIN hand saws the best choice for speed, ease, and quality of cutting.
