Stumpy Nubs may not be the flashiest RU-vid woodworker, but he's by far the most valuable. The amount of education and insight I gain from his videos surpasses any other YT channel, even my favorite ones.

@jameslatour9545 5 лет назад

This made an instant difference in my chisels! When I got my stitches today the Dr. commented on how clean a cut I had. I can’t wait to use them in a day or two again!

I do like this chap: plain, uncluttered advice of real value.

@jimlinn 5 лет назад

It’s very good of you to credit David Charlesworth with this, given that he invented it. I’ve been on all his courses and using his techniques means that sharpening becomes a pleasurable and satisfying experience that is part of the task rather than a chore which has to be got through. I remember his tool tuning course in 2005 which was a revelation; lifts you from clueless to sharpening expert in one week. Once you get your rhythm, the blade is sharpened whilst the tea is brewing. I like the fact that you give logical reasons why - with great little drawings - one should sharpen both sides of all blades.

@brushbros 3 года назад

I am an amateur lapidary. I wonder if a "flat lap" would be of any use to sharpen carpentry tools? They are simply a spinning disk which may be coated or "sintered" diamond of any grit, or an un-coated disk may be faced with wet-or-dry sandpaper. The laps are absolutely flat (especially so since they will be spinning.) Since the motor operates on DC current, their speed may be adjusted. They have a set-up which allows water to be dripped as they spin. And they can flatten an abrasive block too - the diamond is ever-so-much harder than it is (actually flattening sharpening stones also "dresses" the lap, since more of the diamond is exposed.) You have such a nice speaking voice! I like the way you explain yourself too.

@socj1000 5 лет назад

Thanks, Stumpy. It's always nice to learn the basics in such a way that you get the reasons why, so you can 'think with the tools'. Thanks for going the extra mile to explaining it exactly in this fashion!

@hannatree478 5 лет назад

Well, my day's work has just begun. I'm off to the workshop to flatten 10 chisels and three plane blades that can then be sharpened properly. This has been an eye-opener for me. Excellent, detailed explanation of the finer points of sharpening. Thanks Stumpy.

@jota893 Год назад

Times passes but metal and wood persist. I go back to your videos as l learn, and you definitely make a difference.Thank you

I almost didn't watch this because... I know this subject - It's pretty basic. But it's so well done that it IS worth watching - it pulls everything together and makes it very clear. So... Great job. You are a fine communicator Stumpy Nubs.

@harrypowers9412 3 года назад

Great lesson-You are the BEST!

@rowanashby1155 5 лет назад

As the son of a plane maker, former sharpening tutor and a cabinet maker, I could not agree with you more. I used to spend up to a day per blade lapping the backs of the blades by hand for my father's small plane making business. There is nothing more important that a properly flat, straight and square edge. It lays the foundations for properly flat, straight and square workmanship. Thank you for the video.

@noire1001 5 лет назад

If there is a belly on a plane iron you can give it a tap with a plastic mallet and it will straighten it out a fair bit. I got that tip from one of Paul Seller's videos and tested it myself and it really does work.

@stereodreamer23 5 лет назад

i'm a bookbinder, and there is a knife I use for skiving leather that has to be SUPER sharp to shave the edge of leather down to paper-thinness for wrapping round the edge of cover boards. This sharpening technique is one of the first things i was taught as a bookbinder--first you get the bevel sharp, smooth, at the right angle, and mirror-polished. THEN you sharpen and polish the back of the skiving knife. Most skiving knives come from the manufacturer needing a LOT of work--mst of mine have taken several hours of hand-honing on several progressive grits of diamond stones and strops to get them "right". And then every few weeks, I strop and polish them to maintain the edge. it only makes sense that this method would also be appropriate with wood tools too. Great video!

I thought I knew what you were talking about in the first few minutes, then was surprised when you said to polish the whole backside! Then I was surprised again when you went right back into what I've always done, polishing a slight bevel on the back! Was a bit relieved to be honest, lol

@Fireatank 3 года назад

Awesome. Learned this from a German woodworker who told me his first year in the shop as an apprentice was to learn how to sharpen chisels a saws and scrapers etc. Why water stones need to be true prior to use. Very very nice.

@k.b.woodworker3250 5 лет назад

Excellent explanations! I always knew the backs needed to be flat, but have some unused tools, like the least used sizes of chisels, because I never had the time to flatten the backs. Your explanation of the ruler trick was great! I finally understand it and may try it on some planes that I've been meaning to refurbish.

@dothanalabamawoodworker6766 2 года назад

You always do a great job, but diamond stones do not always stay flat. I, and many others, have learned this expensive lesson. Your videos are very helpful.

@StumpyNubs 2 года назад

If your machined steel plate is warping, I don't know what to tell you.

@bleyrad 11 месяцев назад

@@StumpyNubs My Atoma diamond stone got pretty out-of-flat pretty quickly (though it took me much longer to figure out what was going on). As far as I could tell, it's not the machined plate that goes out of flat, but rather a combination of the adhesive that secures the thin diamond plate shifting around slightly, especially after being exposed to water for lubrication/cleaning, and the diamonds themselves wearing more in some areas than others.

@MurrayDrums 5 лет назад

Great tips Stumpy. One you missed was one I got from Paul Sellers! If you have a cheap chisel with a belly on the back, (from end to end rather than across the width) it is possible to put the tool onto a couple of pieces of wood then use a hammer or something to straighten out the blade of the chisel prior to flattening / polishing the back.

@musiq002003 5 лет назад

I want to than you for this video. No one has explained the hollow on the back as in detail like you. This is amazing, thank you again.

@markharris5771 5 лет назад

If they gave Oscars for information on RU-vid this video should win. I was a chef for 25 years and I’ve been sharpening knives for over 40 years, but I sharpened both sides of the edge so I didn’t know any of this science. Thank you.

@bwanasibu4240 5 лет назад

@ThreenaddiesRexMegistus 5 лет назад

A tool will never be sharper than its back. If it’s microscopically pitted or contoured , it’s never going to work well. So many guys I’ve worked with with never understood this simple concept. My chisels used to get a freshen up on the back before the bevel : and this usually just required a quick wipe on a fine hone and finishing on a leather strop . Works with everything from 1/8” paring chisels to 4” Shipwrights slicks. Great video. Subscribed.

@RobRobertson1000 5 лет назад

Hi James, I've been using 'Electrical Tape' instead of the ruler for some years now. It is thinner, it doesn't affect the stones, it gives a perfectly uniform angle as it is taped to the blade itself and going from one grit to another keep the same angle of attack. You don't have to faff around with keeping the ruler from moving around either. AND - I use it on most of my chisels too. If you do the calculations the ruler creates nearly a 1 degree back bevel at 2 inches from the edge (0.9 degrees to be precise). The electrical tape is .14mm thick against at least 0.8mm for the ruler and the resulting angle is a mere 0.14 degrees, still useful to get a quicker mirror face on the back and no real impediment to even paring work. Try it, you'll like it :)

@williambranham6249 5 лет назад

I like the word faff!

@TheSeancassady 5 лет назад

Does the electrical tape hold up during the rubbing or does it start to roll off or become dislodged?

@RobRobertson1000 5 лет назад

@@TheSeancassady No, it glides over my diamond stones without showing signs of wear, and also the Japanese 6000 grit water stone. Obviously, it is a one-time use process. I'm careful to measure and tape it exactly 50mm from the tip so that next time I get the same micro angle. I wouldn't use things like painters tape though. That would break up. Electrical tape is really consistent in thickness too.

@OldToughDW 5 лет назад

Good video! Many wood workers are taught to never sharpen the back of the chisel. That is good advice for novices, and you can ruin a chisel by sharpening it improperly. But as with all tools, if you know what you are doing then you can fix almost any mistake.

I am new to woodworking. My parents flipped houses 40 years ago before it was a thing so I'm not new to tools. However your advice for the woodworker, which is more of an art is very clear and easy to understand. And the additional information and comparisons descriptive illustrations are very helpful to me. A really good balance, not so involved as Paul Sellers advice (I'll have to retire to have that time, but can dream of it) and what is really practical for those of us who want the do it right but with the realistic time frame we have available.
