newbie questions

Fri Mar 29, 2013 9:58 am

I just got a combination waterstone (1k/4k) and I just went by the labels at first. Started with the 1k on my crappy knives then went to the 4k. Later I noticed that the 4k seems a lot more porous and a lot less smooth than the 1k. I was under the impression that it should be the opposite. I feel really stupid posting this.... but I thought the 1k was supposed to be a lot rougher than the 4k. yes/no?

Also I did it free hand because most people don't seem to recommend sharpening guides... but when I drew out a 15deg angle and a 20 deg angle I couldn't really even see much of a difference with my eyes. This is discouraging to me because that means if I can't see a difference, I most certainly am not holding a precise angle to my knife. blah.

a pic might help.

and you might have the grits reversed. =D

Yeah, a picture would be helpful. But, in the interim....

The 4k should feel a lot smoother. Porous I'm not sure, but it should definitely feel smoother. The sound when grinding on a 1k should sound a lot harsher than when on a 4k as well.

So, you're correct.

The angle thing....yeah, that's tough. Over the years, I've learned fairly well what the angle are by looking, but I've been sharpening for a few years now. At the end of the day, one thing I always try to remember....."Does the knife cut well?". If the answer is yes, what does it matter? If it doesn't, maybe you should go thinner/lower angle until it cuts good. If it doesn't cut good until you have an edge that fails easily....that might not be a good knife for you.

As to holding a consistent angle, that gets easier too. You learn to feel the bevel on the stone....you can tell when you wobble. You can also hear it a lot of times too.....the grinding sounds different.

I have a 4k/8k norton combo stone and until i lapped the 8k, it felt coarser than my 1k. Almost had a rubbery/gritty feeling like it was coated. After lapping/flattening it feels like an 8k :)

The light colored side is "usually" the higher grit on a combination stone.

Here it is. Gray feels smoother than white.

try to lap it like sharkbite says with a flattening stone or a diamond plate.

Yes, my norton's 4k is white, the 8k is yellow. Lapping it made all the difference in the world.

Interesting to see this type of problem, I doubt anyone's ever said this about Shaptons... :mrgreen:

Yes, just like the previous have stated, lap those stones. You should notice the 1k will cut faster and the 4k get smoother.

I'm sure you're right Shaun. I know I went 'cheap' combo because I figured I'd end up trashing the stone learning how to sharpen. So far, so good....I've only gouged the 8k badly once :P With my current 'novice' skills, I need a green brick so if I mess it up, there's plenty left to flatten :)
