Hi Jeff, Thank you for another great video. I would like to make a couple of comments. Our Stone stage is $110 retail and its made from excellent materials. To be clear our stones are not made by Shapton. They are completely designed by me and they are being molded for us by a Japanese company. I finish the stones in my shop and glue them to the backing plates myself personally.I cut all the aluminum plates and stages in my shop and a local machinist cuts the holes for our stage in the back. Then I have a local finisher anodize the aluminum for me. Then I do the laser work on the plates in my shop. Finally, I use very high bond tape to attach the stones to the plates in my press. I build every one of them myself. I would note that they are also wider than Shapton as well as thicker. The ponds are also machined for me locally from solid aluminum billets so that accounts for much of the cost. The coating I'm using on both the ponds and the stage is called "hard coat" anodize. It is very tough and cleans very easily. that is also expensive. I know the prices of these things look high at first glance but, my margins are far smaller than you might imagine. The NL-8, our $399 button plate is a good example. It is very flat, yes, but, the cost is primarily in the materials and machining. Those are solid diamond buttons not an electroplated veneer of diamond. You probably can't wear one out hand sharpening. And, if you get it out of flat, I can reflatten it on my lapping machine in my shop. The NL-5 that you are testing is a pattern that I designed specifically for flattening stones. I wanted to maximize the number of edges around the structure and give lots of clearance for the slurry to be pushed out of the way. this also reduces sticking. so, the plate won't stick to the stone as you're flattening. I really appreciate you're review Jeff. If you wan to try my sStone Stage, i'll be glad to send you one for review.

Excellent info thank you for taking the time to clarify that! I think your stones would most definitely give them a run for their money. I prefer the feel of these stones, over the Glass. Those are excellent stones too, but they are a bit soulless. I also understand the pricing being high, but I can't justify spending it. Since I can't justify it, I gotta express it in my videos. That doesn't mean I don't understand. Quite the contrary. The stone holder, the lapping plates, the portable sharpening system, are all nice, but not requirements. The stones on the other hand, I think are priced fairly, especially considering the thickness of them, and how well they hold shape. I am sure every company fights that battle, of cost, vs pricing. All I can determine, is where I should spend my money. The stones have my attention. The other accessories are not required for me.

I'm glad you noticed the differences in feed back from my stones. I worked hard to adjust that balance. I do hope you'll take me up on my stage offer. It has one aspect that i think you'll like. The long smooth sides allow you to hang your finger down and use it as an angle guide when sharpening. With that technique, you can hold a rock solid angle. Also, I like you're trailing edge finishing strokes. I think they are very effective

My advice: Buy your self a double-sided diamond plate, coarse, 600/1200 grit. They never dish and no need to soak them. Then have a fine Japanese whetstone 3000 grit for finishing, and you are good to go for a fragment of the price. NB: Never soak a fine stone (3000 grit+) in water for a long time because it can actually harm the stone and crack it when you use it. Just add som water on top of it and keep it whet that way....

Yeah I think dom bond is right they are upgraded glass stones. The owner used to make the glass stones and be affiliated with shapton. Now he’s on his own I think. Also, I’m really looking forward getting these and trying them. The narrow width was the reason I never got one. An atoma is 65-75 and lasts me at least a year with heavy lapping of Japanese naturals, ceramic stones and silicon carbide stones.

@@bp-hx9ts The problem with that, if the stones is already concave. the sideways angle of the flattening plate is so narrow, it will follow that shape. It will be very difficult to get the stones flat, unless you concentrate on the ends that are high first, then move to the middle. Nice idea, but I don't think it would work well. The length is what helps keep things even along the entire surface. Doing X patterns helps, and there are ways around the narrowness. Just not something I would be satisfied with. As we discussed, just give me a sheet of glass, and some Sic powder.

@@Jef Next month I have an appointment set up with a company that makes very high end 3D surface scanners. They can resolve surface topolology detail to 1/10 of a micron over a 3" x 9" area. We will use it to scan our stones after they have been lapped with our lapping plates. I suspect the results will show that the narrower plate is doing a good job of flattening but I won't know of course until I see the data. I decided to use the narrower design for several reasons. First, the narrower design cuts much faster than the the wider design. Think about a narrow chisel vs a wide chisel, the narrow one will go much deeper into the wood with the same force applied. I have built and sold a wider version (NL-6) It is wider than the stone and I like it for natural stones but, it is not nearly as fast as the narrower design. Second, is cost. The bigger the surface area of the plate, the more expensive it is to manufacture. And, the more rejects we get per lot. Each of these plates is shipped with an inspection sheet that is tied to the serial number of that plate. It shows the measurements taken from that specific plate and where they were taken from. If plates don't meet our minimum standard, we reject them. This process of course is costly. My subjective observation after using these plates to flatten thousands of ceramic surfaces is, that, if one dimension, length or width, is longer or wider than the stone surface then, very flat topology is achievable. There is some technique involved. As Jeff pointed out, you can over lap one area of the stone surface and end up "cockeyed". In my experience, you can do this with any lapping plate of any size by applying pressure unevenly to a specific area of the surface. So, pressure management must be a consideration of lapping. I lap a lot of stones everyday and find that keeping my head out over the stone surface of the stone insures the most even wear.

@collecter3456 5 жыл бұрын

Just turn the plate so that the length of it is on both sides, that way you are covering the whole stone.

I always recommend Shapton Pro. They have an analog on Amazon, called Shapton Kuromaku. Same stones, just made for the overseas markets. They are cheaper, however, than purchasing the Pro series. So you can save yourself a little money there. I would get at least a 3 stone set up. 320 grit, 1000 grit (or 1500 if 1k is unavailable), and 5000 grit. If you have the funds, you can fill in any gaps, you deem necessary. For example, you could get the 2000 grit, to bridge between the 1k and 5k. Or, if you have extremely dull knives, the 120 is an excellent choice. If you are sharpening super wear resistant steels, like s90v, or Maxamet, I would point you towards the Gritomatic Silicon Carbide stones. 240, 1k, 2500 grits, are all you need. If you want a higher polish, look into picking up a Shapton 5k. If you are on a tight budget, King brand is still a solid set, as is the Imanishi stones. The Imanishi 400 latte, 1k/6k combo, will get you where you need to go, in most cases. I have a video up, discussing this topic, located here : kzfaq.info/get/bejne/nMmgpbh5tJq-l6c.html On another note, if you have the funds, the stones in this video, are excellent as well.

🙏 thank you. I’m not really a reviewer per se. Just some yahoo with an iphone and time to spare. I do appreciate the kind words. My videos aren’t always clear so heres a brief summary. The nano hones as stones, are decent. They do not handle new cpm steels with high carbides, but most kitchen cutlery, along with older pocket knives, work really well on them. They are priced a little higher than some higher volume brands, but you do get more abrasive. Surface conditioning plays a huge role in how these stones behave. If you do not have loose sic powder, getting that conditioning correct maybe difficult. I would avoid the diamond lapping plate they sell, just bc of the pricing. It does a fine job conditioning the surface, but it doesn’t justify the cost. Would i purchase a set for myself? No. Although i have praise for the stones, i do not like the pricing scheme, and sales hook, that has been created. It feels misleading to me, esp the hype around “flatness”. Those who may not know any better, can be sold on the gimmick, not knowing where the stones shine, and fall short.

@Jef 4 жыл бұрын

I've heard of that technique, but I was under the impression you needed to rub at least 3 stones together. Something about the randomness of each stone, will help create the flat plane. Using only 2, will cause each one to shape the other, creating a concave. Not sure if any of it is true or not. I normally just use loose Sic powder on glass, and lap them that way. Inexpensive, and effective.

@cactuarizard Жыл бұрын

Micron is an actual measurement of size. The confusion comes from using grit as a standardized measurement. So why should 1000 grit feel so different from Naniwa, Shapton, King, Arkansas, Suehiro, etc. Why should the prices range dramatically if they are all the same grit? Furthermore, more than less people sharpening their knives/tools don’t account for steel type nor the components of the stone. Nano Hone products are a culmination of a person striving to reach perfection as well as the journey there. Hap saw every variable and somehow made them into controlled variables. His line is for enthusiasts. The stones are incredibly dense, give great feedback, and promote the user to learn and use proper technique. Nano Hone’s quality is (in my opinion) equivalent to that of Japanese knife making. You don’t find that kind of integrity often in fucking America. Do yourself a favor. Just don’t buy stones period. Just buy new knives when they get dull. That or develop an educated opinion instead of thoughtless downplays.
