I have two dovetail saws; one’s blade is .018 thick and the second’s is .015. I was skeptical that the .02 marking saw blade would work in the narrower kerf but it’s fine in the .018. I haven’t tried the .015. I use the blade itself to offset the tail piece when scribing, don’t really see the need to use a marking gauge, and that works nicely plus cuts down on the tools at hand. The weight helps. This has become an essential component for me when cutting dovetails.

This marking knife is as advertised. However, Rob does not emphasize just how sturdy this handle is. It is really too heavy for a general purpose marking gauge in my opinion but it is excellent as a dovetail marking knife. The extra sturdiness is much needed in that application. That is what I bought it for so I am very happy with it.

This is a great tool for marking out the pins. Using Rob's method of marking the pins eliminates any struggling of figuring out if you want to cut to the line or cut on the line. This saw tooth blade works wonder along with Rob's saw as they have the same kerf. It makes it so easy as you only need to drop your dovetail saw into the kerf created by this saw tooth blade. Just cut my first ever dovetail practice with this and Rob's saw following Rob's method. Pretty happy with the result and a lot to improve.

This tool is solid and a joy to use. I tried the new method of marking the pins with the tail kerfs and the results were very good. Having a saw kerf to guide your saw on the pin board makes things a whole lot easier and precise.

Comes with a marking knife and saw tooth blade attachment. Easy to switch out as needed. I’ve only used the saw tooth blade as I only use it for dovetails along with the Cosman dovetail saw. Works great, couldn’t be happier and I’d recommend to anyone who buys the Cosman saw (which is awesome).
