I bought a $60 kitchen knife from Chef Knives to Go. This is the exact process I used except I only used a 1000 grit King Neo stone. My knife is smaller but the results were fantastic. Thank you for showing us these techniques. These knives are more fun to work on than a pocket knife. They are more forgiving. Thanks again.

You bet 🤘. I still prefer pocket knives, but hey that’s what i cut my teeth on. Not to mention all the blade shapes and sizes, create challenges. I may piss and moan about them, but they keep me interested.

Holy moly :) Thank you so much for making this video. I watched it all the way through 2 times and really enjoyed your input on sharpening this type of blade made with this specific type of manufacturing process. I will implement your tips as good as I can into my sharpening. I know exactly what you are talking about with these problem areas. A good explaination for this is the taper of the knife from back (a bit thicker) to the front ( a bit thinner) - I can't tell why it is like this for knifes like these but some other "types" of knives have it as well (Nakiri etc.) This is the first full english video (which goes through a full sharpening process) I have seen, in which the knife is laid flat on the stone, like it is ment to be (at least that is what I get from the japanese knife sharpener videos). All the other english videos only focus on the cutting edge, which is fine but does not address stuff like low spots. Thanks again for showing this to us, I hope you can get something from this knife, as the gyuto shape is a nice allrounder. I could not have asked for anything more :) PS: I'm impressed by that end rating on the bess. Do you think the knife can be sharpened to get an even lower score?

If your looking for more videos like this in English check out knife sharpening Norway. Also, the guy i learned most my technique from mredgy. Yes this knife could be thinned out even more, and the edge could be even sharper with a bit more care. The question really is, does it need to be? This low of a score, is ridiculously sharp. We are in the straight razor territory with this score. That means you could comfortably shave your face, with no tugging, or pulling.

Nice work Jef! Nice thing about most Japanese knives is that they use steels with high edge stability, so they can take high performance cutting angles. They also have great cutting geometry grinds, which are usually purpose built. J-Nats are fun, but spendy! I don't think they are worth the money for sharpening kitchen knives vs synthetics for simply a cosmetic purpose. I only have two J-Nats, and they are for razors, and they leave different finishes than synthetic hones. Interesting thing is that one of my synthetics would leave a contrasting finish on the iron cladding and steel core, while neither of the J-Nats would.

Are you kidding? These aren't for cutting! These are for sharpening! Seriously though, that is the ONLY reason I own these two. The first one was for my own curiosity, and sharpening experience. The new one, was viewer requested, and honestly, any excuse to buy a new knife, right? My actual kitchen drawers are full of serrated steak knives, and cook's tools. I do have a couple Henckles, that Connie tried to upgrade me to. They are stashed somewhere in my cabinet, collecting dust.

Gyuto are fun cutters. Lovely stones. I do like my G8.slurry and finger placement will shape the blade road if you are into that method. The primary edge bevel is called koba. I at the finish i do what the nihon call itohiki for 2 to 3 light stropping strokes . It cleans the edge and removes the need to use pasted strops. I am not a fan of pastes but i use them for certain tools to achieve the fastest results in a minimal amount of time.cheers jef and nice video.

The Shapton 120 doesn't sound as loud as the Atoma 140 which is interesting. I thought it would be louder given that it's a larger grit.

Burning macaroni , & messing hot dogs up , sounds like you’ve been eatin some of my cooking . I’ve got a few of the Tojiro white #2 from CKTG the past couple of months to play with on the stones , I’m really impressed by their geometry after removing the cladding from thinning the blade . I’m not a chef & I don’t know if they really needed thinned out or not , but it’s fun doing it .

Oh no doubt. I've heard for the price, those are excellent knives. Like you though, I haven't a clue what is up or down, when it comes to these things. The thinning part is really up to you. If it feels thin, and slices well, then there really isn't much need to do it. They say just going a little at a time, each sharpening, will keep em in shape. As for the burning macaroni, and hot dogs, well that is truth. I forgot both, at different times in my life, when I was cooking. The water boiled out, and what resulted was a mess. I tried deep frying green bean fritters once, and they exploded. Caught the stove on fire and had to break out the fire extinguisher. There was green foam EVERYWHERE.

Seeing progress in my journey to become good at freehand, thanks to videos like yours. Have a couple of recurring issues: one is keeping a consistent bevel from side to side.i struggle when looking down at the knife when pushing it away to sharpen left side. The second issue is I have a tough time removing the burr after going through coarsest stone. I think maybe my burr is getting too large. Any advice would be appreciated. Also, I think you should do some lice sharpening sessions where you answer questions from comments as you sharpen. Would be cool!
@Jef

Never thought about shooting live. Every time i see a live stream quality is garbage or there are internet hiccups. Always something. Consistent bevel sizes may be an issue with the main grind, and not always a result of your sharpening. However, if you notice one side is larger than the other, drop the angle on the smaller side, and try to even it out. In the end, it’s just aesthetics. The knife will still function well, even iff asymmetrical. The burr issue can be tricky. Are you going to finer stones after the coarse? If so just do a few deburring passes on the coarse and keep it moving. As you get finer in grits, the burr will get smaller. That makes it easier to remove the burr on stone, or even strop Hope that helps

Jef Jewell That is all very helpful; thank you for the response! I was trying to make sure the knife was really sharp after first stone before moving onto finer ones. The problem is having a big stubborn burr means it won’t slice through paper or shave hair because the burr is making the edge appear dull. I will do as you suggest and just move on since I know I have in fact reached the apex after getting a burr on both sides. I do think I will try to reduce the size of that initial burr in hopes it will help it not be so hard to remove. As for the uneven bevels, I think it’s a combination of uneven factory grinds and sometimes I go too shallow on the right side. Just seems like I don’t see the angle right when looking down at the knife from that perspective. Something else to work on! Thanks, Jef!

Sorry had a bunch of typos in that reply. I went back and corrected em. Hopefully it made sense 😂 If you wanna test sharpness then yea, as you mentioned, try not to create such a large burr. If you do, there are many ways to minimize, but all require a little patience and practice. Check out steel drake’s videos on burr removal. High angle passes maybe something you find interesting. Or persevere and continue with alternating strokes, until it is clean.

If you don't want to waste an apple you can just rub the blade down with (ideally hot) vinegar. Soak a rag, sponge, or paper towel with vinegar and stick it into the microwave for 30 seconds. Rub the blade for for a minute then rinse and dry. Also, to make use of a bad apple, try frying it up with some butter, sugar, and cinnamon and serving with ice cream or oatmeal.

@@Jef In the case of kitchen knives, this is not done for visual effect, or even for helping ward off rust though it does do that. Were you to have eaten that apple you would almost certainly have noticed a pronounced metallic taste. That is something which will continue until the knife as built up a patina. The reason for forcing a patina here is to prevent that metallic taste in your food.

Just watched from start to finish. Thanks mate. Is your suehiro Product No. CR-4800 - if it is, is the "NEW CERAX" line - silky smooth looks like. For some reason I thought you have the 1010 old "CERAX" which should be closer to the unfortunately discontinued Sigma select II 1200 . However if the blade was better finished at the factory I expect 400-1000-8000 to give even better results than you showed us. One thing I will change slightly is edge trailing strokes on degree or two higher angle for finishing on the G8, at least this is what gives me better results with sigma 6000 (relatively soft).

Hey Jef, random question that I know will be an easy one for you. When sharpening kitchen knives using diamond stones, how far should I refine the edge? I have restored a dull chef's knife to razor sharp using the coarse DMT bench stone, but don't know if I should refine further or keep that toothy edge. What do you think. I have the extra fine DMT I could go to; I also have Norton combo India, an Arkansas soft, and an Arkansas hard. Thanks in advance!
@Jef
@Jef 4 жыл бұрын
That really is totally up to you. Have you tried the knives in use, with each edge? If not, perhaps give that a go. See what you prefer most. I know some like a super high polish, when dealing with fish. Veggies, like tomatoes, others prefer, toothy. Just gotta find what works for you, and your cutting tasks. Me? I take everything to a high polish. Most for aesthetic reasons, but i do like the push cutting capabilities, of that sort of edge.

Do you sharpen on the push or the pull? When I was reading about and learning to sharpen I always read that pressure should be on the forward stroke because if you apply pressure on the pull stroke you're actually tearing out the steel on the microscopic scale, as opposed to grinding it down on the push stroke. But now I see a lot of people talking about sharpening on the pull stroke. Just curious as to your opinion/technique.

Both. I use a weird u shape pattern of pressure. I've talked about it in other videos, and tried to show it as I describe what I am doing. If I can remember which vid it is in, I'll drop a link. My pressure rotates. It is very hard to describe. In theory though, it is in both directions. On my forward stroke, I place more pressure on the tip area than the choil. On my return stroke, I place less pressure on the tip, and more on the choil. It is a U shaped pattern in a sense. I can't recall which video I talked about it in. I think it was a Spyderco knife, but it will take too long for me to go thru em all. If I remember, my next video, I'll go over it again.
