The sharpness result is that the knife got very sharp, as sharp as any other knife I have sharpened. I have a sharpness measuring system - you can watch this video I made on how I use science to measure how sharp a blade is: ruclips.net/video/y_giYbF7qug/видео.html Using these stones I can get the knife sharp enough to score 25BESS on the tester, that is VERY sharp. Most new knives I buy arrive from the factory with a sharpness around 140BESS from the factory, which means I can use these VENEV stones to make the edge over 5 times sharper.
I guess you can call that five times sharp. It might be more informative to describe the apex width as .05 µm. Versus .3 µm at 150 Bess. It’s important to note that only certain steels are capable of being sharpened to under 100.
Something to note: these stones are in the “F” scale, not a typical grit rating, for example F2000 is almost like ~P10,000 (!!) so much finer than you’d think
VEVEV factory measures their stones soley in micron (μ - sometimes written as"um") size of the diamonds,, not the F scale. Gritomatic (the American based retailer) put both the μ and their F equivilent on the the Gemini backing plates when they prepared them for sale in USA. So it SEEMS like the stones are in F scale but in fact even Gritiomatic put both the μ and the f equivilent on batch that I recieved. Of course, they would be free to write whatever they want on the aluminum backer plates. The fact remains that VEVEV measures grit in microns. VENEV stones from the factory do not show the F scale but only the μ size of the diamonds. In micron measuremens the smaller the number means a finer stone. 200μ is the most coarse stone that I use and I have finer stones all the way down to 1μ . (but not in this particular series) You can find a very broad ranging chart made by Gritomaitc., You can view it online or buy it.

I use it almost exactly as I do a typical flat stone, I just have to be very careful to not run the stone off the heel lest I round it off... Oh wait, I think I know what you mean now. Yes, one option is to roll the stone a bit to one side, where it seems to be a bit flatter near the edges of the stone and sharpen the heel that way. OR, what I often do is just use one of these stones for the recurve part and I use a flat stone to the the heel of the blade and the belly of the blade - of course, that only works if the recurve doesn't go all the way deeply into the heel of the blade. Another type of stone I have that can help me if its too complex is the BORIDE brand narrow stones. Those are narrow enough to be used for many recurve blades and they will get the heel done well. I prefer the VENEV curved stones because they get the job done faster and they are great even for premium steels that are quite hard. I hope I haven't confused the issue with my extra long reply.
@@CanadianCuttingEdge No, I understood it all. I have narrow stones, but they are only good for knives with a slight curvature. For really curvy and small knives, like karambits, the left edge of a narrow stone creates deep cuts into the bevel. Think I just have to live with not being able to sharpen the heel. After all, who uses the heel?

Industrial merely means they are not good enough cosmetically to be used in jewelry. I am very familiar with them, I worked with industrial diamonds with my father for several years - he had a custom tool and die shop and he installed them on parts he sold to Timken (the bearing company). Man made diamonds are called either "cultured" or "engineered".
another awesome lecture from the fine faculty at CCEU. Thanks for sharing, Jake.
Thank you! I try to find good educators to speak here at CCEU.
Those stones looks great even for using it by hand I like hand sharpening and only have 1 recurve knife.
By hand, it would require a lot of good hand-eye coordination but I can see that working for some people.
I have a number of recurved blades of different lengths. I've been using sharpening rods and honing rods for a workable edge. I think I'll try these.
Rods are also a GREAT option for sharpening recurve blades.
I just got 3 today, and now they know come with a very nice aluminum base , and it also says the grit # on the back in english.
Yes, I saw some since I made this video. very nice indeed.
I’m going to get some of the Venev curved diamond stones. Do I need the F80 grit or can I start with a finer grit? What do you recommend?
For recurve work you can generally start a bit finer, the 80 is just needed if you are going to repair some NASTY sections of blade.
Sur where is the sharpness result pls i want to see it. If you can’t can you pls make a full video🥺

Nicely done
Thank you! Cheers!
Where do you buy the narrow blanks?

How does the stone handle the heel of an edge? Do you have to tilt it for the stone to make contact?
I use it almost exactly as I do a typical flat stone, I just have to be very careful to not run the stone off the heel lest I round it off...

Dont do as i do, do as i say!!! Hmmmi wonder where ive heard that before!!!?? Ahhhhpolitics😂
I made this video a while ago, so I cannot recall what context you are referring too, so I can't really respond either.

Industrial diamonds are man made
Industrial merely means they are not good enough cosmetically to be used in jewelry. I am very familiar with them, I worked with industrial diamonds with my father for several years - he had a custom tool and die shop and he installed them on parts he sold to Timken (the bearing company).
