I have a couple bigger projects that I keep on putting off. I don’t feel particularly motivated to finish them right now with everything on shutdown, especially since even if I do finish it, I can’t deliver it until quarantine is over. So… woodworking procrastination

I don’t even remember how I decided to make a marking knife. The one I use right now is fine. I must have come across an article or Instagram post or something. Actually, I think maybe it was because Blue Spruce Toolworks makes some amazing tools. Right now, they are having a sale. I was tempted to buy their marking knife but it’s a good chunk of change so I decided to try and make one (same thing happened with the mallet).

I looked online for various methods and decided upon using an old jigsaw blade. I cut it down (1/4” wide, 2 1/4” long) with my grinder, did some shaping and sharpening and turned a handle out of some olivewood I found a while back. I used part of a brass tube from a pen kit as the ferrule. Looking forward to putting it to use.

Looks good, did you heat treat the blade? For me that’s half the fun:)

Thanks! I didn’t heat treat the blade. I haven’t ventured much into metalworking. It looks really fun but I need to get some more equipment before I can try it. I just took the jigsaw blade as is, slowly ground it while trying not to overheat it so I wouldn’t lose the temper. That should be ok right?

Nice marking knife! The blade should be fine, and shouldn’t need a heat treat.

I just made a couple squares as a procrastination project. Next up is a clamp rack. Then maybe I’ll get onto the project I’m actually supposed to be getting done…

That’s really really nice. I tried making one a few years ago. Got the handle turned but was never satisfied with the blade and the crummy looking ferrule. I’ll have to give your method a try. Thanks for posting.

That turned out VERY nice. You have every right to be proud.

Looks like it’s store bought with that being meant as a compliment. I made one years ago from an old spade bit after seeing it done in some woodworking publication. Turned out well but not nearly as useful as your design which allows reaching into much tighter spaces. I do have some similar ones to yours that I have acquired over the years.

Thanks! Yeah, there are so many little things to do and make around the shop that distract me

Thanks! yeah, the jigsaw blade worked really well, it’s thin but stiff enough for a marking knife. Hope yours turns out great!

Thanks! Yeah, as I looked at various methods, people use all kinds of stuff… table saw blade, jointer blade, spade bit, tool steel, hacksaw blade, and other random stuff. Using a jigsaw blade seemed to work the best for the kind of projects I do
