I tried out a Swann-Morton scalpel as recommended by Paul Sellers and found it to be a good marking knife for dovetail work. I got the scalpel (sold as a handle alone) and a box of 50 blades (SM01) from a UK seller on eBay for about $20 Cdn.

After making a batch of 10 (out of scrap – cherry, walnut, etc.), I went on to make more and have given some of them away as gifts. These knives can be:
- precision marking knives
- hobby craft knives, or
- box cutters, depending on who receive them!

You can cut the blind channel on the tablesaw as I did, on the router table or by hand if you’re just making one or two (like cutting a hinge mortise). Make sure the channel is carefully cut so the blade sits snugly and tightly in it.

Caution: These SM01 blades are super sharp.

You can use other blades to make your own knives:

- Stanley Utility Replacement Blade 11-041

- X-ACTO blades

-- The time I enjoy wasting is not time wasted
