Bench Top Woodworking Tool – Ergonomic Marking Knife

Ergonomic Marking Knife

I have made marking knives in the past but no longer have them so when I needed to make a mark line other than a pencil line I figured it was time to make one. I purchased some 1/16″ 01 tool steel off of Amazon, found a piece of maple and began to get to work. Fortunately I had some carving knives I made a while ago and used them to shape the handle. I was hoping for a handle that “felt right” in my hand and I believe I accomplished that. The blade is a single bevel with a flat reverse face. I like this kind of knife rather than the ones that are made for the left and right hand separately. Just can’t get my head around the reasoning for needing two knives when one like this works right or left hand. A knife with a single bevel has a tendency to force itself into the straight edge you’re using and to me it’s a bit of a problem because the knife’s sharp edge may mar the edge of the ruler. To help prevent that I put a small back bevel (5 degrees) on the flat side. That corrects the problem. Sometimes I will use the knife in ways other than simply marking a line and is a good reason why I won’t make the blade thicker than 1/16″. In fact one of the marking knives I had was made from a bi-metal hacksaw blade and was a favorite. The thin blade was useful getting into small areas. If you haven’t made a marking knife for yourself I suggest you do so, it’s a¬†worthy¬†endeavor, a pleasure to make and use your own.

    How is the blade in your marking knife attached to the handle. I don’t see any holes for rivets. I’m thinking of making one from an old recipricating saw blade and was thinking that it would be difficult to drill holes through that.

      Hi Jake. The blade was first roughed up with coarse sandpaper, then cleaned. I epoxied the blade into the slot. I have found that the epoxy makes for a strong enough bond without using any rivets at all. As far as drilling through a reciprocating saw blade, you might try using a cobalt drill, that might work. I would suggest though using O1 tool steel. You can get it at Amazon at a reasonable price. It is easy to drill, cut or bend to the shape you want then heat with a propane torch to harden. That is what I used. An advantage to using the O1 bar stock is that you would have more steel left over for other projects like carving knives. I use O1 steel for those also and pleased with the outcome. Good luck.
