A Marking Knife Bakeoff for the Budget Conscious

When I was new to woodworking, I didn’t see much use for marking knives. But, people whose work I admired used them regularly, so I tried them. And my joinery improved. Marking knives have contributed to tighter, more accurate and better-fitting joints for me.

Mind you I’d prefer to own one of these exquisite beauties by Blue Spruce Toolworks:

But the $65+ price tag was more than my limited tool fund and priorities could bear. So I drafted knives lying around. And I made a couple of my own. Soon, I had six knives cluttering precious bench space. So I resolved to whittle them down to one by testing each in pine, oak and maple end grain.

Here are the marking knife contestants:

1. Utility knife (box cutter)
2. Swiss Army knife (main blade)
3. Stanley 10-049 utility knife. Paul Sellers turned me on to this option in his post here.
4. X-ACTO blade (#26 Whittling Blade)
5. Homemade marking knife with repurposed sabersaw blade
6. Homemade spearpoint marking knife, with repurposed sabersaw blade

And here are closeups of the cutting edges:


Round 1-Pine crosscut

Well, the utility knife (1) and both my shop-made (5, 6) knives performed poorly. The remaining three (2, 3, 4) were judged on the criterion of clean, crisp and narrow gauge. Based on that, I ranked them 3, 2, 4.

Round 1 goes to the Stanley utility knife.

Round 2-Oak crosscut

All six were competitive, but again the bottom three marks were 1, 5 and 6. Following the same criterion as above, I ranked the remaining three: 3, 4, 2.

Round 2 goes to the Stanley utility knife.

Round 3-Maple endgrain dovetail marks

For dovetail marking, I eliminated 1 and 5. 6 did ok for one mark but not the other. 2 also did ok but the mark was not well defined nor deep. That left 3 and 4. And to mine eye, 4 made the better cut with 3 close behind.

Round three goes to X-ACTO.

And the winner is…

1. The Stanley utility knife (3.) It was the best all-around and is a very reasonably priced tool suitable for marking.
2. Coming in second was the X-ACTO knife (4) #24 whittling blade. Some users may prefer the pencil-style handle versus the flat handle of the Stanley.
3. Taking the Show Position was the Swiss Army pocketknife (2.) I liked the curved blade which consistently severed the wood fibers effectively and easily. However, its large size made it cumbersome to mark tight dovetail spaces.

I should note that both my homemade equivalents did poorly. That made it easy to get rid of them. I also found new places for the other marking tools. So today, my sole marking knife is the Stanley10-049 utility knife.

Nice write up and test, Brad. I went through a couple marking knives (one purchased and one made in the shop) before investing in a marking knife from David Barron a couple years ago. Have never regretted that decision.

Interesting test. Why do you believe some knives performed poorly; or to put it another way, what trait of the best knives allowed them to cut better?

Well Rick, I think that the Stanley blade edge is finer and longer. My spearpoint shopmade edges just didn’t cut as well. Maybe you have had better luck.

JayT, the David Barron marking knives are certainly beautiful. I like the finger-grip dimples, brass ferrule, blades and wood species. However, their high price puts them in the same category as the Blue Spruce knives in my opinion.

I was just asking. I have a marking knife made from a Swann Morton blade which is very similar to your #3. I like it but the blade is a bit long and flexible but it works very well. I also made a knife from a sawzall blade and it works well. I haven’t done the same head to head testing though to directly compare them but I might now.
