When I was a kid I was taught a basic version of the three plate method to get a brick or block flat enough to sharpen tools. My old man was a mason, and we didn't need a lot of super sharp tools, but sometimes you did and a flat enough block/brick wasn't always available. The three plate method is overkill for most needs. If you just take two blocks, get some water between them and rub them back and forth in a somewhat random pattern including some turns and flipping which one is on top, you'll have a flat enough surface in a couple minutes. That's pretty much all you need for most garden tools and such. Even without a strop, you can use a red brick to get a knife blade shaving sharp as long as you flatten it first.

This proves that the "right way" to sharpen is to pick a method, any method, and work to develop the skill. At the end of the day it doesn't matter how you get to a sharp edge, just that you have the skill to make and maintain one.

Sharpening is one of those things that seemed very daunting when I first had to sharpen, mainly because many youtubers make so big a deal of it. But then I just decided to get a 40$ whetstone sharpening kit from Amazon with two stones (grits 400/1000 & 3000/8000) and just sorta went for it. Turns out it's not that hard at all.

I started with something similar. A double sided 400/1000 diamond stone, and a strop with green compound. I even glued the leather upside down. Everything still worked great. (As a tip for others, soft "drawer liner" works great. Put your stone on top of it to keep it from sliding around.) I've since moved on to Rex Krueger's "Cheap, thin diamond plates & strop glued to a melamine board". Rex's video compliments this one very well. James: "You don't need anything special to get your tools sharp. See, you can even do it with a rock." Rex: "So stop overthinking things. Just use stuff that is cheap and practical."

When I'm in the middle of something is when I find the shortcuts to sharpening, case in point yesterday scrubbing a large block of Matai (NZ native) with a Record 5 1/2 plane, realised it was not sharp enough. In the middle of a mess of odd tools and wood offcuts, disorganised chaotic shed right now as I'm shifting it around, just hunted around for any old whetstone, and found a can of wd40 as liquid, so there's enough to get a fairly decent edge fairly quickly even though the aton was too small to get a proper motion just carefully do back and forth angled sideways. Amazing difference.

I had done extensive testing just to improve my knowledge and once i was at a big box store and found a super cheap Aluminum oxide stone for like $5 and bought it to challenge myself if i can get a good edge - low and behold i managed to EASILY get a shaving edge from just that stone and a strop (not even leather , just scrap mdf) ... To make sharpening even faster with cheap oil stones , grinding a primary bevel with a bench grinder to get a hollow grind and then just doing like 4 seconds on the stone gives you a tiny secondary bevel in an instant and easily polished on the strop ... And no need for any fancy grinder , just a normal high speed grinder second hand off marketplace with a diy tool rest is fine

I don't have a problem with getting an edge. My father, may he rest in peace, taught me to sharpen by sound. A grating sound means it's too much toward the heel. A grinding sound is just right at the face. A scratching sound means it's too much on the edge. Those are not technical terms and are pretty subjective, of course, but it worked once I heard him do it. My problem is with keeping the edge square to the tool! My chisel ends up angled, my plane iron angles the other way, etc. I imagine it's just more practice and adjusting elbow and wrist angles. I never tried concrete, but my father would use a river stone to sharpen his pocket knife when he was fly fishing. Thanks for your clear, simple explanations!

Bascially the thing youtuber should teach is : get a burr , strop it, get back to the bench. i like to wander in the how to also .. sometime i do figure of 8 (Paul Sellers), sommetime i go staraigth, when i need to change the bevel angle i do it holding the edge in the same way i sharpen not perpendicularry). all of this because i noticed that that was the way I (capital, bold underlined) was able to hold my edge straigth, it s just the best for me ( capital, bold underlined). a burr, a stropped edge and happy shavings!

I've looked at a sharpening stone, a natural cobblestone, cracked length wise by a Chinese miner/store proprietor. The piece is set into a piece of liveoak log, and the fracture surface has a glassy polished surface. It has been worn into a saddle form by intense use. It was probably used to sharpen kitchen and butchering tools. I glue the strop to a piece of wood with hide glue - heh. Provides a firm surface with less tendency to round the back immediately behind the edge.

When people ask for "the right way" I simply point to tradition. We've been doing it in x way for hundreds of years, it probably works. In this case that's a grindstone, a wheel. However I must add that since about a hundred years we've made steel much harder and also since about the same time carborundum has been the material for said sharpening stones rather than sandstone. In fact I bet we got much harder tools after carborundum (a synthetic material) was invented as a sharpening stone, because it sharpens much faster than sandstone. So it allowed tools to become harder. I must also add that handheld (or laid down?) sharpening stones have also existed for a long time. But given that it's a lot more work that way I assume it was more for maintaining the edge rather than forming and repairing an edge. Or perhaps because stones that sharpen very thinly are more rare and thus aren't made into big chunks like sandstone was.

@WoodByWrightHowTo Жыл бұрын

Acquiring the skill to sharpen makes perfect sense. I honing my sharpening skills. 😉 I watched most of the sharpening KZfaq videos from Cosman, Rex, You, Sellers, Katz-Moses, Stumpy Nubs and many more. The only remaining question I have is does angle matter for edge retention, if so how much. An ancient Boy Scout leader decades ago told me that a 30° angle will hold an edge the longest. Myth or magic at 30°?

@WoodByWrightHowTo Жыл бұрын

The short answer is yes. The higher the angle the longer the edge will last. But the harder it is to push into the wood. So different tools can be put in different angles or some people just pick one angle for every tool in the shop. Here's a video where I go into more detail on it. kzfaq.info/get/bejne/l9SjqZCl0NrQlps.html

You have covered so much, thanks for clearing up 30° question.

@autumn5592 Жыл бұрын

A more acute angle will hold the edge longer, but wont handle lateral forces as well, so making chipping and rolling easier. So 20° will stay sharper longer than 30°, but you can't hammer it into wood and expect it to maintain the edge as well. You should use whatever edge angle you prefer the most. Experiment by reducing angle gradually every sharpening until it no longer holds up as well as you'd like, then go up a degree or so, and you will be at the ideal angle.

I think sharpening is a bit of an internet problem. We access to so many different people presenting different methods with different mediums etc. We only have to think a little to realise 30 years ago you would have such more limited exposure to different methods, generally one person showing you how they did it so you learn to do it like that. In the bigger picture people had to do this to earn a living, day in, day out. They learned to use what they had and got it done. What's not often discussed or overlooked, is the beginner with a cheap chisel(s) that will just never hold a good edge. They could be using perfect technique but they feel it is technique or sharpening stone holding them back when really it could actually be the steel the tool is made from.
