Rob Cosman's Marking Gauge
The second most important tool in cutting dovetails is your marking gauge. The gauge line becomes part of the finished joint. Here is why I think my marking gauge will help you cut better dovetails:
The blade comes to you sharpened; designed to sever the wood fibers not crush them, leaving a crisp gauge line.
The blade is fixed in use but can be rotated to a sharper area when it gets dull. You can do this several times before having to resharpen.
Has a flat section on the brass head preventing the gauge from rolling off of your bench.
The face of the head is dead flat, making for precise work.
Has a large knurled locking knob that is easy to tighten.
Comes standard with the 1/2" diameter cutter head.
Extra cutter heads available in 3/8", 7/16", and 5/8" diameters.

The handle is crafted form the same Ebony Swanstone composite material as our saw handles.
Other species of wood handled marking gauges are occasionally available in limited manufacturing runs. You can see these limited edition marking gauges by clicking HERE.
I wish I would have found this marking gauge to begin with. I've purchased a couple different ones from Woodcraft and Lee Valley over the year, but this one stands above them all. Don't waste your money shopping around, this one will leave you completely satisfied and it's well worth the money. Feels more solid in your hand, and does an excellent job marking projects.
The finish on the Rob Cosman marking gauge was perfect with everthing finely fitted and has a good overall balance. All you have to do to lock the rod in place is just snug the screw down and it holds. Not like some other gauges where you almost have to take a set of pliers to it.
Rob has the best tools for woodworking! Thank you!
Really nice Piece of equipment Nice sharp cutter and positive lock Very pleased I bought it.
I have owned the Veritas version of this round-cutter marking gauge for years. I thought it was perfectly adequate. That just goes to show that you don't know what you don't know. The Veritas version of this gauge has a screw head holding the cutter that extends beyond the cutter itself, which makes the process of capturing the thickness of anything pretty much a guessing game compared to Rob's version. In addition, Rob's has a reassuring amount of heft to it which makes it seem more stable somehow. Not to mention that it is razer sharp out of the box. Oh – and the flat spot makes the thing stay where you put it rather than rolling around on your bench and possibly hitting the floor. I plan to buy a second one of these gauges to facilitate the dovetail cutting process, as per Rob's videos. (Watch them if you don't know what I mean.) It's that good.
