Cutting tiny dovetails (dovetails in 3/8 inch and less thick stock) is a bit challenging if using my regular sized dovetail saw - it can be done, but I wanted a better saw for this application.  That is why I designed my 3/4 dovetail saw.   As compared to my regular-sized dovetail saw, the 3/4 dovetail saw's thinner saw plate, smaller teeth, shallower depth of cut, and shorter overall length, makes cutting tiny dovetails a breeze.

My 3/4 Dovetail Saw is perfect for small box makers, cutting joints in small drawers, and anytime you are rip cutting 3/8 inch or less stock.  My 3/4 Dovetail Saw is the best saw on the market for rip sawing tiny joinery.  And just like our regular-sized dovetail and Joinery saws, it leaves a smooth, ready-to-glue, finished surface.

I designed my 3/4 Dovetail saw with a thin .015 inch blade; 22 teeth per inch (TPI), filed rip along the entire tooth line; and a minimal .002 inch set per side. The relaxed cutting angle of the small front teeth allows you to start the cut with ease - a major issue with other saws!  The teeth, cut with a diamond-saw, slice cleanly and precisely through wood fibers.  The minimal set creates a small .019 inch sized kerf that guides the saw straight in the cut while the shallow 1-3/16 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.

Product Details:

  • Size. Overall length (Toe to Handle tip): 13-1/2 inches.  Blade length (Toe to heal): 8 inches. Depth of plate under the back: 1-3/16 inches.

  • Weight: 12.50 ounces (+/- 0.5 ounces). 

  • Blade. Each of our 3/4 Dovetail Saw blades are made from .015 inch thick, spring steel.

  • Tooth Geometry.  Filed rip with a two-stage pitch. The first 1-1/2 inches is filed at 22 teeth per inch (TPI) with a 30 degree negative tooth rake, which allows you to easily start a cut. The rest of the blade is filed at 22 TPI with a 0 degree tooth rake allowing you to finish the cut with just a few strokes.

  • 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 .019 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: Rob Cosman dovetail saws have a 1/4 inch thick x 3/4 inch 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 providing you a better balanced saw, allows the saw and gravity to do the cutting work, and helps you "feel" perpendicular.

  • Handle. Our unique "pistol grip" handle has 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 3/4 Dovetail Saw handles are available in 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.
