Every hand-tool woodworker needs a minimum of three backsaws: Dovetail, Tenon, and Crosscut Saws. I design and manufacture two Professional Tenon Saws to meet this requirement: my Large and Medium Tenon Saws. 

My Large Tenon Saw is built for the professional or advanced hobbyist woodworker.  Its size and weight provides you the capability to cut even the largest tenons, however; it requires that you have already mastered the skills to control the saw. My Medium Tenon Saw is built for the hobby woodworker and is specifically designed to make learning how to cut tenons easy.

Both of my tenon saws are heavier than most providing you with better saw balance and reduced vibration. The weight, combined with the pistol grip style handle, trains you to make straight, perpendicular cuts. The relaxed cutting angle of the small front teeth starts the cut with ease and the diamond-saw formed teeth slice straight through the wood giving you a ready-to-joint surface.

This saw is designed for the professional or advanced hobbyist woodworker.  Its size and weight provides you the capability to cut even the largest tenons, however; it requires that you have already mastered the skills to control the saw. The 20 TPI teeth with a relaxed cutting angle on the first two inches of the blade makes for easy saw starts, 12 TPI teeth on the rest of the saw quickly and efficiently makes precise cuts in the densest hardwoods. 2-3/4" depth of blade allows you to handle very large tenon cuts. and the.025" thick blade; provides the stiffness needed in a large saw.

    Product Details:
    • Size. Overall length (Toe to handle tip): 17 inches.  Blade length (Toe to heal): 12 inches.  Depth of blade under the back: 2-3/4 inches.

    • Weight: 22-24 ounces. 

    • Blade:  Made from .025 thick, spring steel.

    • Tooth Geometry: First 2" are filed rip at 20 TPI with a negative 30 degree rake. The remaining teeth are filed rip at 12 teeth per inch (TPI) and a negative 10 degree rake.

    • Set: Unlike most saw manufacturers who stamp out their saw teeth, leaving "dimples" in the blade, we individually cut out each of our saw teeth with diamond impregnated saws.  This allows us to maintain a very slight set of only .002 inch (per side), since we don't introduce that "dimple" onto the blade.  This slight set produces a narrow .029 inch kerf that eliminates slop allowing the saw blade to accurately track in the saw kerf resulting in dead straight saw cuts with smooth ready to glue surfaces.

    • Brass Back: 1/4″ thick x 1″ wide brass back is secured to the blade with peened and flushed copper pins.  Not only does the brass look wonderful but it imparts extra weight to the saw, as compared to our competitors saws, that provides you a better balanced saw, allows the saw to do the cutting work, and helps you "feel" perpendicular.

    • Handle: Each of our "pistol grip" handles have memory enhancing carved finger recesses for a perfect and comfortable fit. A pair of brass split nuts secures the handle to the blade and the brass back.  Our tenon saws come standard with handles made from ebony Swanstone, a composite material reinforced with glass for durability.
