Highland Woodworking has published my “Sharpen This – the Hand-tool Backlash” speech that I gave at the Lie-Nielsen Open House a couple years ago. You can read the whole thing in Highland’s newsletter here.
(Note: You can subscribe to the free newsletter here and also read all the back issues.)
Chris Bagby at Highland asked if I would tweak a few sentences of the speech to take it from an R rating to a solid PG. But he didn’t ask me to pull any punches. So now the speech is an article called “Sharpen Up or Shut Up.” It’s basically the same speech but without a few Bozo-no-no words and my Southern preacher imitation.
Check it out. And if you like it, you might like the short series I wrote for the blog (also free). You can check that out here.
Next Saturday, Sept. 9, is our regularly scheduled open day for Lost Art Press. We’ll have our complete line of books plus a good number of slightly damaged books at 50 percent of retail (cash only). And T-shirts. Coffee. Stickers.
I also have been informed that we will have a handful of Crucible dividers there that are cosmetic seconds (100 percent fully bang-on functional). Those also will be 50 percent of retail (cash only).
It’s ‘Sharpenday’ To reinforce the “Sharpen This” series of blog posts, I will offer free sharpening lessons all day. If you want to learn basic sharpening or get into more advanced topics, come on down. I don’t know everything about sharpening, but I’ll be happy to share what I do know.
(Note: Let’s not make this day about me rehabbing your old or damaged tools. If you’d like to bring in a tool to discuss, great. I’ll show you how to sharpen it, but you will do the grinding and honing. One guy brought in a box of old planes for me to fix for him once – that service is $60/hour plus materials.)
If you struggle with any aspect of sharpening, put your ego aside and come ask for guidance. If you don’t know how to sharpen curved blades (travishers or scorps), we can cover that. Scrapers? Yup. Grinding V-tools? Nope (those drive me nuts).
Some days I wish there were a Google Translate filter for woodworking forums and podcasts. It would allow people to understand what is really being said. Below are some actual quotes I’ve heard through the years and my rough translation of them.
Statement: “As soon as you pick up a hand tool you are losing money.”
Translation: “I can’t sharpen.”
Statement: “Some of my students went down the hand-tool route and became frustrated when the tools didn’t do what was promised.”
Translation: “I cannot sharpen, and I encourage my students to skip it.”
Statement:
“With reverent pause, I turn on the switch
And submit to the roar and the sounds that bewitch.
Abrasion, vibration, my only sensations
My art I pursue of instant creations.”
Translation: “I can’t sharpen or write poetry.”
Statement: “To the last, I grapple with thee; From Hell’s heart, I stab at thee; For hate’s sake, I spit my last breath at thee.”
Translation: “Wanna find out if I can sharpen, whale?”
Statement: “When tools were rude, great precision and nicety of finish could not be expected. To return to the crude joints of our ancestors would be a distinctly retrograde move.”
Translation: “I cuddle with my Kreg Jig.”
Statement: “Let machinery be honest – and make its own machine buildings and its own machine furniture; let it make its chairs and tables of stamped aluminum if it likes: Why not?”

When it comes to the topic of honing guides, I’d sooner have a double colonoscopy than discuss them. But here goes.
Honing guides are jigs. They hold a cutter to perform an operation, much like a scratch stock holds a moulding cutter, a slitting gauge holds a knife for cutting veneer or a router holds a dovetail bit for cutting joinery. Sometimes jigs are a good idea; sometimes they are a fool’s errand.
But to dismiss them entirely relegates you to the realm of woodworkers who populate the food court at the Woodworking Show, yammering to the ketchup dispenser about the finer points of mustard. Don’t be that guy.
As someone who has used almost every honing guide on the planet and who started life as a devoted freehand sharpener, here’s my take: You can’t do all of your sharpening with a honing guide (or the accessories to the accessories for the honing guide). But you’re also a fool if you don’t acknowledge that a simple honing guide can bring consistency and speed to sharpening simple blades.
If you want to explore honing guides, first buy the cheapest one – the Chinese-made side-clamp honing guide that costs $10 to $20. This is one case where spending a lot of money isn’t a great idea. Expensive honing guides are usually part of some sort of system, like Amway.
Try the honing guide. Compare its edges to the edges you get when you sharpen freehand. And – whatever you do – make your decision without consulting the Internet. It will only radicalize you one way or the other.
Personally I use a honing guide for straight chisels and simple plane blades. Everything else – moulding plane cutters, carving tools, knives, weird chisels, awls, etc. – are sharpened freehand. And when I’m working in the field, I sharpen chisels and bench plane blades freehand – it’s not difficult, stressful or even inconvenient.
I use a guide at times because, like all jigs, it can speed the operation of routine chores (I think of it like using a table saw for ripping lots of lumber). But I’d never use a honing guide that required a setup time of more than two minutes – by that time I’d have the edge sharp and ready to go back to work.
But most of all, don’t let any debate about sharpening equipment or techniques get in the way of your sharpening.

One of the misguided mantras in sharpening is this: Polish the edge until you remove all the scratches left from the previous grit. Then move to the next finer stone and remove all the scratches left by the earlier grit.
This ridiculousness is why it can take beginning sharpeners 30 minutes to sharpen a chisel.
Polishing doesn’t make the edge sharper (see this), it makes the edge more durable. So having a few errant scratches remaining on your edge means you might have to sharpen a little sooner than if you had achieved a perfect scratch-free edge.
Sharpening priests and priestesses will counter my statement with: Tiny scratches in the edge will leave tiny scratches on the work when using a smooth plane.
To which, I’ll counter: Yes, but sandpaper. (See this entry for a discussion of the traditional way to prepare surfaces for finishing.)
Coarse scratches left by manufacturing, grinding or a coarse stone.
Scratches left by a #1,000-grit waterstone with a few deep scratches visible.
Polishing on a #4,000-grit waterstone with a few errant scratches noted.
Polishing with an #8,000-grit waterstone with one scratch noted.
Sanity on Scratches When you polish an edge, a few errant scratches are fine. When I sharpen on a polishing stone, here are the steps:
Rub the bevel on the stone for about 10-12 strokes.
Observe the bevel; if there are scratches, return to step 1.
If there are still scratches after three visits to a stone, I move up to the next grit (or get back to work if that’s my final grit).
Sometimes I manage to remove all the scratches from an edge. Sometimes I don’t. Regardless, sharpening a tool never takes longer than one song on the radio.
On Cleanliness One of the ways to improve your polishing has nothing to do with the brand of stones or your skill. It’s cleanliness.
In my experience, the primary cause of scratches that are difficult to polish out is stray grit on your sharpening stones. If you get big rocks on your small-rock stones, the big rocks will scratch the edge. These big rocks can be loose abrasive on the stone or even get embedded in a soft stone.
So keep your stones clean. If a stone is giving you trouble, put some lubricant on it and wipe it off with your hand. That removes loose grit. If grit has become embedded in the stone, flatten the stone and clean it off. That fixes almost every problem except for a stone that was poorly made and has coarse grit embedded throughout (yes, this happens).
