Rob Cosman Medium Tenon Saw – Rip Cut

Product Description

What Rob says

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

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

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.

After watching thousands of my students struggle to learn how to use large tenon saws, I decided to design a tenon saw for the beginner and weekend woodworker. My Medium Tenon Saw is the result. It’s slightly smaller than my Large Tenon Saw, making it easier to control and use, but it’s still big enough to meet 90% of all your tenon-cutting requirements.

22 TPI teeth with a relaxed cutting angle on the first two inches (51 mm) of the blade make for super-easy saw starts; after that, the 12 TPI teeth cut quickly through your stock. A 2 inch (51 mm) depth of blade makes balancing and controlling the saw easier than my Large Tenon Saw.

Product Details

• Size. Overall length (toe to handle tip): 15-7/8 inches (403 mm). Blade length (toe to heel): 11 inches (279 mm). Depth of blade under the back: 2 inches (51 mm)
• Weight 20–22 ounces (567–624 g)
• Blade. Made from .025 inch (0.64 mm) thick spring steel.
• Tooth Geometry. First 2 inches (51 mm) are filed rip at 22 TPI with a –30° rake. The remaining teeth are filed rip at 12 TPI with a 0° rake.
• Set. Unlike most saw manufacturers who stamp out their saw teeth, leaving “dimples” in the blade, we individually cut each tooth with diamond-impregnated saws. This allows us to maintain a very slight set of only .002 inch (0.05 mm) per side, since we don’t introduce that “dimple” onto the blade. This slight set produces a narrow .029 inch (0.74 mm) kerf that eliminates slop, allowing the saw blade to track accurately in the kerf, resulting in dead-straight saw cuts with smooth, ready-to-glue surfaces.
• Brass Back. 1/4 inch (6 mm) thick by15/16 inch (24 mm) wide brass back, 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, compared to competitors’ saws, providing better balance, allowing the saw to do the work, and helping you “feel” perpendicular.
• Handle. Each of our pistol-grip handles has memory-enhancing carved finger recesses for a perfect, comfortable fit. A pair of brass split nuts secures the handle to the blade and the brass back. Our handles are made from Richlite, an incredibly durable, sustainable, and versatile material made from high-grade FSC-certified paper infused with a thermosetting resin.
• Handle Size & Determining Your Size. Handles come in two sizes: Regular and Large. Please refer to the picture above showing how to measure your hand and determine which handle size is correct for you.
