I don’t think angle cube would give you an acceptable reading to figure out if you’re hitting apex. It’s not that precise. Checking for burr is much much more accurate and easier approach. To answer your second question – no. Why would you do it? Sharpie is useful when you try to match existing angle. That happens before you even begin sharpening. Unless I’m missing something here and the question is in fact loaded.

Thank you all for the replies. Clay, when you strop, if I understood you correctly, you’re not reducing the angle as some have suggested? You also move straight from the 1000 to the leather strops? With a micro bevel, do you go back to 100 grit and raise a burr or simply use the 800 or 1000 grit stones and run a few passes? I’ll be sure to do a search for micro bevels and check out the suggestions and videos.

Not reducing angle before stropping – Think of it as a convex micro bevel (Clay, please correct me if I’m wrong)

Micro bevel question – you don’t need to raise burr. Blade should be sharp at this point. Use 800 or 1000 stones with edge leading strokes. Just a few (like 2-3-4) very light strokes per side. Almost no pressure.

What about nano cloth? Is it cleanable?

I’ve never tried to clean it, but I think it would difficult to remove grit from within the matrix of fibers. It’s probably like cleaning carpet – you can only get it so clean.

I didn’t mean to clean it to a near brand new state so one could apply different abrasive compound. I was rather thinking about metal particles that might eventually clog it. With diamond film I need to clean it after each use, otherwise performance quickly degrades. With leather I occasionally reapply abrasive compounds on top of what’s already on it without much cleaning. With nano I’m not sure if I can treat it like leather – add same abrasive on top of whatever’s on the strop already.

It hasn’t been an issue yet, since I only use nano to put toothy microbevels. But at some point I’ll need to deal with it, I think.

Interesting. I tried it today on 2 Henkels knives – chefs and pairing. Both were sharpened at 18 dps. One side 1000 grit, the other one is 100. No microbevels. No stropping either.

Results are some what mixed. It did reasonably well with chopping, using chef’s knife. But it felt a bit uncomfortable. Pure slicing was very nice, though. With pairing knife I had a whole lamb leg separating it to muscles. Definitely better than expected.

Now, while it was an interesting test, would I employ it on my regular kitchen knives? I’m using Takeshi Saji R2 knives in my kitchen (sharpened at 12 dps). The answer would be – no. They are more versatile as is, IMHO. But for some projects this idea has a potential.

Clay, were you cutting straight down or at an angle (kinda like sushi chefs do)?

[dima]

Then you probably need to start with soliciting input from the owner. Does she like how it performs now? Does the blade get dull quicker than anticipated? And so on and so forth. Also, how hard is the steel? This bit is important.

And, in most cases, you can contact the manufacturer, if she preferred the original angle. More often than not they tend to be helpful.

Any particular problem with the original sharpening angle?

I have used these when I had access to a friend’s Edge Pro—they are fantastic. I used them at the original angle, then widened the angle and hit the apex with something toothier…it is a great combo. Question, b/c of their cost, which one or 2 should I buy if I sharpen up to 1000 grit?

According to the grit comparison chart, 1000 grit is around 7 micron. I remember, Clay mentioned that with stropping you need to go back a bit with grit because properties of diamond plate differ from lapping film. Which means you’d need to continue with 9 micron lapping film even though it might seem counterproductive. So, to answer your question – 9 and 6 micron. I could be mistaken, though.

I was mistaken, it looks like. In his latest YouTube video Clay goes from 1000 grit to 6 micron lapping film (and then to 3 micron)

I’d think you can either mark blade with a sharpie, or put blade on a paper sheet and mark spot on paper (you’ll need to outline blade profile on that paper). Or something along these lines

Not sure about going for it bit ? I really don’t need level of magnification scope like this offers, and getting it just to see how it works doesn’t make too much sense. Adapter itself is not that expensive, but these scopes are quite pricey. On the other hand, if there’s WEPS user in Northern California that already has the scope, I’m willing to get the adapter so we could get together and try it.

Actually their tech said that combined magnification of camera and adapter is about 12x, so it’d give about 1200x magnification with 100x objective.

Did anybody try these?

They have Canon adapter as well … If it works, that might be an ultimate solution for both, focus stacking and HDR

[dima]

Would low angle adapter work for this? I’m just curious…
