000Robert, when I’m finding the “sweet spot”, (i.e., the best or most efficient position to clamp the knife for sharpening), using a sharpie, I use a very fine stone or often even lapping films, with a very wide or obtuse stone angle setting. All I’m trying to do is remove the sharpie ink, just barely touching the edge with the stone, without removing any steel, while adjusting the clamping position. I’m simply determining how efficiently the stone contacts the knife’s edge apex as it’s positioned and clamped.
Once I have the knife positioned and clamped in this best position, then I start adjusting the stone angles, more acutely, to determine what the angle actually is, as I remove the sharpie ink from across the entire bevel height. Then last, I measure and record the stone angles where I get complete removal of the sharpie ink from the full bevel, shoulder to apex. For me it’s a multistep, multipurpose process. (My issue with the hobbygoni is, I sharpen mostly chef’s knives. These knives can often be too tall to fit in the circular frame of the goniometer. IMO, just measuring the bevel angle at the shorter height of the knife’s tip, (the only knife portion that would fit in the device), is not a true representation of the actual knife’s bevel angle and therefore an expensive device for limited use. I find many knives as they’re forged, have a narrow bevel angled tip where the steel is often thinner, also).
MarcH Maybe this one is something for your knives: https://sharpeningtool.eu/de/catalog/accessories

I thought that we were not supposed to check angles with a coarse stone? And I advise you guys to wear a N95 mask when you are sharpening knives with any system. It is the particles and dust that you do not see, that you breathe in…IMHO
Before sharpening I determine the angle with the catra hobbygoni. That will be my guideline. The sharpy test is only to check if the knife is in the right place in the clamp.
Veel plezier hier.

@MarcH it is not an video of my. It is from an American knife maker, CK knives and tools.

I use it also, look at my YouTube film about stropping the benchmade 940-1

If I lived in America, I would order the A. And then ask Mike Brubacher for the new ATF-10G and KF-10R. The only reason I have a B is because I have to pay more than 50% in tax and shipping in the Netherlands, if I order something from abroad. This is the e-mail address of Mike.
Send him an e-mail and he will answer all your questions.
