    How This Tool Is Built

    We started with a sharper edge, but we didn't stop there. Vanquish vibration, say adios to constant resharpening, and let wispy shavings fly. Delivering superior performance at your lathe drives our manufacturing. 

    We’ve worked with M42 high speed steel for decades, and it’s uniquely suited for woodturning. You’ll grind less - a cobalt additive bumps M42’s red hardness off the charts for impressive wear resistance. And the steel produces a finer, sharper edge for clean cuts. M42 is a win-win: less grinding and smoother cuts. 

    Our M42 starts as solid stock and is precision machined (not formed) with a unique round tang and unmatched strength. 

    Rigorous and detailed sums up our manufacturing. Each tool’s vibration-demolishing round tang has a diameter so precise you’ll hear a ‘pop’ when you pull it out of the handle. Gouge flutes are meticulously polished for the sharpest edge. And every tool leaves our factory razor sharp and backed by a 100% lifetime guarantee. Built to last!

    Rest assured our aluminum handles feel as great as they look. Perfectly weighted for balance and maneuverability, and designed to fit your hand. You’ll forget the handle is even there, in the best way possible. Two set screws secure your tool into the handle and allow removal for sharpening.

    From flute polish to handle knurling, we’re not cutting corners. Whether you’re just starting out, or have been turning for decades, it’s an honor to serve you with quality tools. Learn more about our story and the tools right here

    Great service and great tools

    Great tools and service. The email notification of shipment is very helpful. The tools arrived packed very well and sharp ready for work.

    Mahoney + Carter M42 = the Bees Knees!!!

    The shear scrape is one of my most frequently used maneuvers. While I do enjoy the push cut to create a tear-out-free result, I really rely upon the shear scrape for refinement of shape. What's more, being self taught from Mike's videos has really helped me enjoy successful bowl turning. Now having a premium M42 gouge made in the USA coupled with the keenest edge in M42 I have been able to obtain I am able to focus exclusively on the shaping of my turnings. No more lathe-grinder-lathe-grinder dance due to edges that drop off when shear scraping. Thank you for a superior product and offering the finest parabolic M42 gouge I have ever used.
