For outdoor knives, I've noticed the same inconsistent deep scratches on my SG 220. Story time; this is for @DrMatt357 I was playing with my new Gritomatic 120 trying to turn my Tops Tanimboca into a zero-degree scandi-grind. After using the Gritomatic 120 on the primary grind, moved to the SG 220. The SG 220 was cutting slower, but causing these weird inconsistently deep scratches. The Gritomatic 120 cut faster and had smoother consistent scratch patterns. The issue is if you move up from the SG 220 to a 400 grit, that stone will polish over the scratches instead of buffing them out. Between my experience and yours, I don't think I'll ever buy another Shapton Glass stone again. Also, I'm well aware I was doing needless rebeveling and polishing. It's what I like to do... DrMatt357, you have an underrated channel.

I know the Shapton glass stones are supposed to be a harder stone. From my experience in my trade I usually find the hardness of material matters when it comes to how much it deforms other materials. In my trade that means I uses brass to hammer steel pins in place or bend steel piano wire as its not going to deform the steel, but I believe the same principle happens with sharpening. The Shapton 16k stone tends to advertise being a longer lasting stone with less ware and it would make sense to me that this would mean it would cause that kind of damage. The reason a strop works is because it is softer and has a bit more give in it allowing the metal to fold around and deform the surface a bit while the polishing compound takes material away and straitens it. I would hypothesize that softer stone would do a similar thing to a strop. Obviously a softer stone will be harder than a strop, but in side by side comparisons obviously this is on a spectrum. I know that shapton 16k stone is nice for establishing bevels and rounds on plane blades and a final polishing on a chisel. But those are much harder metals than what is desired on a razor. It would be interesting to do the same test with both stones on metals of varying hardness. For example try this on a rockwell 62 chisel and compare and even throw in a strop. I could certainly be wrong as I am basing this completely on how well my hand planes and chisels cut hardwood, but I think the distinction could be interesting. And if there is a difference, then what is the ideal stone for various harnesses.

Very informative, Dr. Matt. The other take away I got from this video besides the effects of over honing on a Shapton 16 glass stone is what you said at around 4:49 that you have seen the same thing happen on a coticule stone. I think that the real lesson is that the Shapton 16K stone gets the edge so thin and sharp at the beginning of honing that any continued contact with the cutting protrusions of the stone will chip the thin brittle metal of the edge. Thus the theory of over honing. Please correct me if I'm wrong.
@drmatt357
3 жыл бұрын
That's one possible theory but I don't think it's as much as the razor's edge getting too thin but an issue with the stone because obviously the razor's edge was just as thin when using the Naniwa 12SS and it was fine.

It's been a while since the last time I was sharpening a straight razor. I've been using a Boker Damascus made with powder steel and the edge of this razor is wonderful even after several shaves. I just use the strop one in while. I also have another Boker special edition that I don't use, it's too pretty for daily usage. However, I also have the Boker king cutter and that one I have to maintain daily with the strop and sharpen it quite often. Many years ago, when I used to use the king cutter, I realized that the Nortom 4000/8000 gave me a better result than the shapton glass 16000. Years after, I understood that there are differences in the way of measuring the grid and that these numbers only apply in the serial grid for each brand. But after seeing this video, I will never use my shapton glass stones with my expensive razors. These stones looks more suitable for knives.

The S glass stones get a bad rap. Something went wrong perhaps while lapping. Give the Shapton a rub with a coticle slurry stone dilute slowly one time or surface burnish lightly with a hard steel. They also cut too fast so jump strait to running water an five strokes. I use my SG hones to rub the next SG as i work a progression. 1K, diamond lap once in a while 1k laps the 3k, which laps the 6k, which laps the 8, the 10, the 16, the 30... rust eraser to rub swarf away. .... That said your 8k and one well chosen finisher plan is a keeper.

The shapton 12k does the exact same thing. It will leave a rougher edge than an 8k. I read it has something to do with not particle size, but particle distribution, that does that to the edge.

Dr Matt, I enjoyed your video on the 16000 shapton. In fact you kept me from purchasing one. Howard over at the perfect edge honed a razor for me about 8 years ago. He used a shapton progression on my razor, it was the 1000,4000,8000,16000 & 30,000. It was to this day the sharpest and smoothest edge I’ve ever had on a razor. After watching your video, I’m confused to say the least. Could you comment on this please?

Shapton is a fast cutting stone. When using one, you should limit to only a few passes on the stone, do not go more than 10 because it is useless and then the edge might weaken. That’s all. With other stones, you can do more passes as they are slow cutting.
@stuartmaxwell6013

I am also confused, because there is a video on here of Howard going through his progression, and he swears by these Shapton glass stones. He does at least 40 laps on the 16k by my reckoning and he goes at it hammer and tongs. I notice that at the very end of his process, after the 30k, he kills the edge - is that removing the chips? I don't get it.

I think what happens here is, you have taken the razor super fine... and then you are grinding the razor down to a lower grit... and you are probably creating a super tiny wire, and it is breaking off causing the chips... or some sort of steel formation from actually grinding down. Would the same happen going from a 8k to a 5k? probably... just not as badly because the edge is not as thin. Naniwa stones load up and bernish a TON compared to glass stones... That is my explanation. Super stones are hands down my favorite razor stones. They kinda suck for knives though.. because they don't grind and wear quickly!

Shapton is known THROUGHOUT THEIR LINE for putting non-uniform sized grit in their stones. The larger sized grit included along with the "correct" sized grit leaves deeper scratches that can't be polished out. Consequently, you get a more jagged and less polished edge. Unfortunately, the only way you can see it is under a microscope.

I have found that I only use the Nan/12 at only a damped state and not pooled up water, when used at a barley damp state I find it finishes finer, and I will not chip the edge, because its a fairly soft stone, and it auto slurries. I finish with 25-30 passes on the Nan/12!! What kind of scope? Stereo? What brand? I wish they made a HC series in the 16k! The HC 8k is IMO one of the best 8k synth stones.The HC series is much more finer and polishes more than it cuts, if that makes sense, for a synth stone Thanks Mike

@@drmatt357 yes - sir, the gray ones. They are are not as aggressive and much more for carbon steels the 'white' HR are for super hard, wood working plane steel. The HC stone are more elastic, and forgiving. The HC still work on harder Swedish steel, and stainless. Which grit do you have in the HC? A 8k? Man I would like you do do a deep scope look at its finish after say 30 laps. I borrowed one (8k)from a friend on B&B and man that thing finished IMO like a 10k!! I don't have a scope just a 10x loupe , but it would be nice to see what it looks like. Thank you Matt. . Mike The one I use is the Kuromaku stones, they are good but I find they do scratch deep, for their grit rating. They are kinda like the Chosera stones, meaning the dame binder and all. Mine are still nearly 15mm thick and I have honed quite a bit on them. I am going to sell them and put up some more and buy the HC glass. Lol - unfortunately its a bad time of year to sell these puppies, they have been up for sale for 2 months on B&B.

That’s a good question. I believe that by using slurry, you would ease some of that chippy edge thing and it would be smoother. Problem with that is you also lose some of the keenness to the edge with the slurry.

To my eyes, somthing is not looking right here. The scratch pattern and the (chips) presented on the blade in the photos, including the micro large bends in the blade. Do not fit the pattern on the blade. With some common sense and a little experience, anyone could see the photos to the description & scratch patterns are not adding up. However for this to be the case the viewer has to be looking with unbiased eyes. I personally have never touched a Shapton stone ever. I'm an Ark and Naniwa guy. I also am not saying a Sharpton 16k can or cannot chip a blade. What I am saying from 20+ experience sharpening with a microscope as I do electronic work and have always had a good scope. In these photo's the chips and bends in the blade edge do not look as if they came from the same stone that put that scratch pattern on the blade. Not saying how this guy did this. Just say it was not done how he states it was done.

Don't trust anyone who has a motive for altering the results depending on revenue streams. Wanna know how to alter the results from any hone? Just change the pressure. I can set a bevel on a Naniwa 12k SuperStone. I can put a shaving edge on virtually any 1k hone. How? By proper use of pressure. Wanna make a hone you don't sell look bad? Just jack up the honing pressure.
