I followed Rob Cosman’s new way to cut dovetails in which the waste is retained between tails when marking pins using this marking knife with the sawtooth blade that fits in the kerf created by his excellent dovetail saw. His process and knife delivered just as he expected: close fitting dovetails without the need for chisel corrections! I need more practice and flat stock (I used pine boards of soffit material that wasn’t exactly flat). A great system of technique and tools.

I was having trouble getting consistently tight fitting dovetails just marking with a pencil. Sometimes I'd get small gaps. Using this for marking and marking before I remove the waste has eliminated that problem for me. Using the kerf this makes to start my saw cuts. I'm getting great fits now.

It's not the marking knife that makes the difference. Its the entire concept. Robs tools are the best available anywhere but the methodology is what makes the dovetails work. Rob must have a chronic bruise on his forehead. I've tried to make dovetails for many years only to give up in frustration. My wife says I'm much easier to live with now.

This saw has such a fine kerf, it’s amazing. Even in my novice hands it preforms spectacularly.

Its seems like a simple thing to accomplish what this is doing; But having this tool for its specific use is incredibly time saving and helps with consistency. Buy once, cry once!
