I've been sharpening knives for ~3 years now and have basically just been doing my own thing. My knives have always come out sharp... but in hindsight, its probably just becasue it was just trial and error where I just sharpen until it's sharp and the first half of sharpening I was probably not doing anything/hurting the knife! This is so helpful!!!

A burr is like steel peanut butter. The grit of the stone drags metal off the bevel, and it hangs on at the new apex you are forming. Some guys with a SEM (Scanning Electron Microscope) photographed two types of burrs which form, one for softer steels, and one for harder steels. The softer steel is easier to de-burr. If you think of peanut butter clinging to the edge of a butter knife as you spread it, that's what the steel does when you grind a knife on a whetstone: it clings to the apex. If you have a USB microscope, and want to see a big burr, to form a picture of what one looks like, take a knife and grind it on a sanding belt. That will leave a huge burr for you to inspect.

Thanks for this - I just bought the Nigara AS/S Tsuchime Kiritsuke Gyuto from you guys. I love it but wouldn't think to throw it through my 3 stage electric sharpener. I have a good whetstone set but always got discouraged when I tried to use it. I will try the quarter and thimble trick on some of my beater knives to see if I can get a nice sharp edge. Thanks for all the content and for your great customer service. I will be a return customer for sure!

@user-pm7pw1tl3t 6 месяцев назад

I love how many "pro" sharpening videos there are yet they cant even make the scratch pattern go the same direction on both sides

@jacmac0422 2 месяца назад

Why would that matter? I understand if you are thinning or sharpening a wide bevel but why would the tiny primary bevel matter. He is going for performance not a mirror edge.

Use plastic angle guides, about $10 bucks. They're little plastic chips that have a slot for a rubber band to hold them onto your whetstone, so you can re-check your angle at any time. They come in sets, angles from 10 to 20, IIRC. You can stack 10 and 15 if you want 25 for a cleaver. Holding an angle is like learning to ride a bicycle. At first, it seems impossible and you fall a lot unless you have training wheels. After m-a-n-y hours of practice, you finally get it! (Then you can move on to a unicycle! And sharpen to sub-50 Bess.)

@KnifewearKnives 2 года назад

Great advice! We sell some plastic guides that we love.

I have a question regarding the soaking and non-soaking stones. I currently purchased a combo whetstone (#1000/#6000) and was wondering if I can soak the whole stone or do I just soak half of the stone (#1000 side) since #6000 is a fine non-soaking stone.

@KnifewearKnives Год назад

Hey there! I would just soak the 1000 grit side. Some 6000 grits like arashiyama benefit from soaking, but others can crack.

@MikeJustice1993 Год назад

Do you always need to start sharpening with a coarse stone like a 220 grit or can you start with a 1000 grit then move to 6000 grit for finishing? I only ask because I bought a combination stone and was wondering if I needed to get another. Thanks!

@KnifewearKnives Год назад

Not at all! If the knife is dull you do need to start on a coarse stone, as starting on 1000 will take too long. If it's in decent shape still, you can start on 1000. Np need to finish a softer western knife on anything finer, but Japanese knives usually benefit from polishing higher than 1000 grit!

@MichaelKWang 3 года назад

How much pressure are you using with your fingers on the knife? And is it applied in both push and pull directions?

@KnifewearKnives 3 года назад

Generally a very gentle pressure, never pushing hard, and definitely in both directions!

@appleseed666 2 года назад

When you are pushing the knife spine side facing away from you, are you only putting pressure on the blade in the forward motion? Same question for when you flip the knife with the spine facing towards you, do you only put pressure when pulling the knife back?

@KnifewearKnives 2 года назад

Good question! We apply pressure in both directions, it makes the sharpening go twice as fast!

@petersss Год назад

I have a Knifewear 220 Grit Truing Stone - is that an acceptable replacement for a 220 whetstone to use for sharpening?

@KnifewearKnives Год назад

Unfortunately they're made differently and the trying stone doesn't contain all the abrasive of the regular 220, but in a pinch it would probably work.

@michaellinnett7786 Год назад

any guidance on what coins to use in Australia to achieve 15 or 22.5 degrees? I'm mostly interested in 22.5 degrees as my best knives are German and the rest no-name

@michaellinnett7786 Год назад

mucking with Australian coins and an iPhone leveler app, a 20c spacer and 5 x 20c coins gets around 22-24 degrees - close enough for me

@MatthewG9631 Год назад

Hello, are you using US nickels to measure the angle or will the US nickels be different? thanks!

@KnifewearKnives Год назад

They're only slightly different, so they'll work!

@paulneumann7739 3 года назад

I have a question regarding evenly sharpening sides. I have noticed that I must grind-whetstone quite a bit off the first side to create a burr. When i go to do the second side, it creates a burr in much less strokes than the first side (since it is asymmetrical) do I keep grinding on whetstone second side to make sure both sides are perfectly even? I came up with a counter system- thumb thimbles and measuring tape...I have 3 thimbles to represent each side. Heel-mid-tip...I count 15 strokes on each part of knife and advance the respective thimble one step Just wondering if both sides should be even come the end of the sharpening? ie does this make the knife blade "weak or dull faster"?

@KnifewearKnives 3 года назад

Hey, good question! Most people sharpen the same side first every time, which creates an edge biased to one side. This is totally fine! Most people won't notice it and it won't have a serious effect on the knifes performance, although it may cut subtly to one side. It sounds like your method for balancing it is great! Another option is to start on the right side one time, the left side the next time, and so on, but that can be hard to remember. Doing a set number of strokes per side until you raise a burr is a surefire way to keep it balanced!

@paulneumann7739 3 года назад

Thank you! I will figure out how many strokes I can do to maker this even on cheap knives.

@JulieIelasi-lt7yp Месяц назад

An i sharpen my everyday Chinese Cleaver this same way too with your Japanese sharpening way ?

@KnifewearKnives Месяц назад

Yes, absolutely!

@nielsvanos3114 3 года назад

Why are you removing the burr with the honing rod after each stone instead of using the 'peanut butter method'? Thanks

@KnifewearKnives 3 года назад

Good question! The spreading method works well, but still leaves a substantial burr. The honing rod clears it up fully so we don't get a false positive when we're raising a burr on the next stone!

@jaredcook4577 3 года назад

@@KnifewearKnives why is the peanut butter method even considered a method then if its not ideal? This sharpening stuff drives me bonkers as everybody has a thousand opinions 😂

@sacoto98 3 года назад

What is the difference between the nagura stone and the bigger flatening stone? Can't they serve the same purpose?

@KnifewearKnives 3 года назад

They can! The nagura stone works like an eraser, cleaning grit off of your fine stones. You won't want to flatten finer stones with every use, so the nagura keeps them clear and working well. You can just use a truing stone, but you wouldn't want to use a nagura in place of a truing stone.

@sacoto98 3 года назад

@@KnifewearKnives so the nagura is a much gentler approach more suited for fine stones but not enough for coarse stones

@jvh136 11 месяцев назад

No coins required for 15 degrees. Tangent (opposite over adjacent) of 15 degrees is 0.25. So raised the spine 25% the height of the blade. For 20 degrees it would be 36%, not so easy to eyeball.

@passportazul 3 года назад

I know they are similar, but are we talking US nickels or Canadian?

@KnifewearKnives 3 года назад

Great question! We're based in Canada, so we use Canadian nickles.

pull toward you sharp push away blunt repeat thie cycle over & over you are wasting ur time edge wont b sharp u are just removig to much metal & frustration sets in this video perfect if you want a blunt knife

@KnifewearKnives 10 месяцев назад

This is a common misconception, but not reality. Working in one direction just means you're moving half as much steel as you could be, and makes it harder to keep a consistent angle. Once you're removed your burr, you're got new geometry for your edge! Hope this helps.
