Marking Knife

The method of making this one is more or less the mainstream way to do it. Not a whole lot of elements I can credit myself with.

The wood is Mahogany. I started out with a 6” length similar to the size of a pen blank. The wooden part itself ended at about 5.25 ” after turning and such. The goal here was to keep it small. It fits my hand in a manner that gives good control. There’s better designs for marking large areas or sheet goods. This is more of a finesse tool I use for dovetails and more intricate parts.

The ferrule started out as a standard hexagon nut. I drilled out the interior of the nut to make a 5/16” hole. I then did some very rough grinding on a grinder (little thing gets hot fast) and then used my Worksharp 3000 to sand it to a circle. I used lathe powered buffer to give it more of a polished look.

The blade is a jig saw blade. I used a planer knife prior and found the jig saw blade was easier to work and just as stable for the job. Grinding off the teeth and coating only takes a few minutes on a grinding wheel or stationary sander. I used both. The bevels were made freehand on the Workshop unit. I didn’t get carried away with sharpening it. It doesn’t need to be sharpened like a chisel for it’s function. I used some epoxy on the tang and ferrule to ensure all stays still.

Nice job, Jeff. The knife looks great. I hadn’t heard of using a standard hex nut for the ferrule before, I’ll have to ferret that one away for the future.

I also just made one of these, pretty much the same way as you did here. Did you find that the tiny bevels were super difficult to sharpen? I may have to make a jig if I make many more of these. Or maybe I just need practice (never hurt I suppose).

Thanks for sharing, I love seeing shop-made tools.

Hey Brian. I actually commented on your knife when you posted it recently. As I said there, this has been on my short list a while and decided to give it a go after you posted your Paduak one. I also checked out Cohen’s how-to for some procedural ideas.

As for the bevels, I made two blades using a planer knife in a failed attempt before this one. It was very hard to get them to “look” even. I might have just been luckier on the jig saw blade, but I was able to work it sharp and even without issue. I used a Worksharp unit for the bevels with a high grit paper. Since it’s a flat spinning disc, it wasn’t too hard to free hand. I didn’t even try it on a grinding wheel. Cohen made a jig for a Tormek wheel that looks complicated but gives good results.

Looks like a nice marking knife. Congratulations.

This should be like Facebook with a like button. It’s a good looking knife and I hadn’t thought of using a nut. Not much I can add.———- Like
