Yet another saw in the series. Until this project and the research I have done into this, I did not even know that this variety of hand saw existed. I found the information on it in a blog called the Norse Woodsmith. I do not have a dado blade for my table saw and I hate resetting my router over and over again, so typically to cut a dado I will set the table saw blade height to the depth of the dado, run 2 cross cuts through the width I need, and then chisel out between the cuts. This saw allows me to use the same method of work via hand tools, and will make it easier to cut stopped dados as well. I started with a section of saw blade steel harvested from a off the shelf miter saw from the local BORG. I am using the toothed section of the miter saw in a different project (to be coming in the near future) so I needed to cut the teeth into this steel from scratch. Then I chopped the wood blank from a section of poplar, and there we go. A nice hand tool. took it for a bit of a test drive and it cuts like a champ.

For more info on the saw and details to the process I used to make it you can see my blog at

Thanks for looking.

Very interesting …..I see by the teeth that yours is a pull saw while the original pictured in your blog is a push saw. Is it just the pictures or does your blade cut deeper closer to the rear handle or is it adjustable for different dadoes ? Thank you. : )

Dusty I think its the pictures that make the blade look uneven, It’s not set with a micrometer, but using a 3/8 inch chisel as a depth set, it’s close enough to even to work for me.

I did choose to set the teeth as a pull saw, I generally prefer to work with a pull saw so that’s the choice I made here. I’ll possibly switch it around after I use it a while if the push seems to make more sense.

I have thought about making some additional holes in the blade to allow me to set the depth of the cut deeper if I need to. Kind of a cool idea I thought to make it depth adjustable. I haven’t done that yet, but the thought has crossed my mind
