What is a Kerfmaker?

The Kerfmaker is a tool that simplifies the process of making accurately sized grooves, dados and half-lap joints. Even half-lap joints that are not at a 90° angle are very easy to make with this tool. Once it is adjusted for the cutter and stock width, it is used as a spacer against a fixed stop to accurately cut both sides of the groove. It’s perfect for cutting dados for sheet goods, which often vary in thickness, as well as box and drawer making, and half-lap joints.
It is perfect for: Frame work, box makers, carcass work, drawer making and the list goes on and on. It is a tool that once used, you will never want to lose.

Interesting!

I remember when they were all the rage! I think I have the one I made somewhere. Mine wasn't as nice as yours!

Every once in a while I use it. There are other ways that work quite well. 

Thanks Rick.
