Rob Cosman's Professional Joinery Crosscut Saw
Every hand-tool woodworker needs a minimum of three backsaws: Dovetail, Tenon, and Crosscut Saws. I designed and manufacture two different professional Crosscut Saws: my Joinery Crosscut and my Bench Crosscut to meet this requirement.
Both of my crosscut saws are specialized for crosscutting applications. My Joinery Crosscut Saw is designed for making finished, ready-to-glue joinery cuts. My Bench Crosscut Saw is designed for general crosscutting tasks.
I designed my Joinery Crosscut Saw with a thin .020 inch blade, fine 15 tpi teeth filed crosscut, and a minimal 2000th of an inch set per side. The teeth, formed with a diamond-saw, slice cleanly and precisely through cross-grain wood fibers.
The minimal set creates a small kerf that guides the saw straight in the crosscut while the shallow 1-5/8 inch depth of blade (tooth-line to brass back) helps with stability while sawing to a line. The pistol grip handle conforms to your hand for a perfect, repeatable fit every time.

Size: Overall length (Toe to handle tip): 15-1/8 inches. Blade length (Toe to heal): 10 inches. Depth of blade under the back: 1-5/8 inches.
Weight: 18-20 ounces.
Blade: Made from .020" thick, spring steel.
Tooth Geometry: Filed crosscut at 15 teeth per inch (TPI) and a 0 degree tooth 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 a diamond saw. 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 .024 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: The brass back is 1/4″ thick x 7/8″ wide and is secured to the blade with peened and flushed copper pins. Not only does the brass look wonderful it imparts extra weight to the saw providing you a better balanced saw. This enables 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 crosscut saw handles are made of ebony Swanstone, a resin-composite material reinforced with glass for durability.
Handle Size & Determining your Size: Our handles come in two sizes: Regular and Large. Please refer to the picture above showing how to measure your hand and determine what size handle is correct for you size hand.
From the very first cut, this became my favorite saw. Clean, straight, fine and feels amazing in the hand. I'm a novice woodworker, and I didn't convince myself to go for the purchase until I had a significant project on my hands where I knew I'd use it. I'd been using a decent Japanese pull saw, which could get the job done, but the difference of using the Joinery Crosscut was amazing. The fit to hand, the easy of holding the angle and keeping the cut true, and the ability for the saw to maintain such a straight cut once the kerf is started. Not only does this saw get the job done, but it feels incredible -- second only to pulling perfect shavings from a hand plane. Well designed and worth every hard-earned penny!
Outstanding saw! A bit pricey but partly goes to a good cause.
Its a great saw and gives me joy every time I go to use it. I have even been reaching for this saw to make cross cuts over my 12" sliding compound mitresaw and I'm a trim/custom cabinet maker for the last 10 years. The way the saw feels in the hand with it's balance and the calming sound of it cutting the fibers is soothing to the ears. Can't wait to build up the bank account so I can add to the collection by purchasing the rest of the saw line up. Thanks Cosmans for designing something well worth the money.
I am impressed. In all honestly I was not confident in making joinery straight from the cut but Robs joinery crosscut saw cuts so precise and smooth it leaves a perfect wood surface for glue ups. It leaves a perfect knife cut edge I'm absolutely blown away how well it cuts . The saw has a great feel and the weight is spot on, do yourself a favor and get one.
The Crosscut saw is every bit as amazing as your dovetail saw. It seems hard to understand the cost delta - UNITL you make the first cut - then it all makes sense. I have purchased many other handsaws, but none of them compare to the cut quality and accuracy of Rob Cosman saws. Your products are amazing!
