Rob Cosman's Joinery Crosscut Saw
Every hand-tool woodworker needs a minimum of three backsaws: Dovetail, Tenon, and Crosscut Saws. I designed and manufacture two different 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 cross cutting tasks.
I designed my Joinery Crosscut Saw with a thin .020 inch blade, fine 15 tpi teeth filed crosscut, and a minimal .002 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.
My Favorite Saw
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!
It worked very well but I think I need to get some wax to reduce the drag. Do you sell the wax stick you use? I have thought about making the Paul Sellers oil in a can he uses also. What do think about the oil in a can compared to the wax stick?
Joinery Cross Cut Saw
Great product. I wish I would have purchased this sooner
I have several western style saws. The weight and ease of the cut on the Cosman saws are noticeably better. Easy start and smooth cuts.
So much better than vintage
I’ve been working exclusively with vintage backsaws that I recently learned to restore and sharpen. The level of precision that this saw affords is just amazing, coupled with the extra weight from the heavier brass back and the composite handle make this saw an absolute joy to use.
