    How This Tool Is Built

    We start with the sharpest edge, and we don'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 4 decades, and it’s uniquely suited to woodturning. You’ll grind less - a cobalt additive provides unparalleled edge holding. And the steel produces a finer, sharper edge for clean cuts. M42 is a win-win: less grinding and smoother cuts. 

    Our carefully sourced M42 starts as solid stock and is precision machined (not formed) with a unique round tang for unmatched strength. Every gouge sports a distinctive flute polish. This boosts the razor edge and provides efficient chip flow. Learn more about M42 HSS here.

    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. 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 here

    Goodbye Sandpaper

    Wow I finely was able to use my new Mahoney Parabolic Shear Shaper and I could not be happier. The results I am getting are incredible, a much smoother finish on my projects. Make sure you view Mikes YouTube video on how to use the tool, I found it very helpful. The folks at Carter and Son build outstanding tools and provide outstanding service. The company is a pleasure to do business with and I look forward to purchasing more turning tools in the future. All I can say is Carter and Son and Mike Mahoney make a great team.
    Happy turning.

    I like it a great deal

    Quality you can feel

    Although I am in the middle of moving into a new shop and am not set up for turning yet, I can't wait to get at it. Just holding this shaper in my hand and feeling the balance and weight, then feeling the sharpness of the edge, you don't have to touch it to the wood, the shavings are being sliced off in my mind and you can just feel the quality. I am very happy with this purchase, and I have 3 more gouges on the way.
