Thread: Norton 4k after Chosera 1K ?

Good day to you all. Yesterday i got my chosera stone, brcause i was disappointed by my Norton 1000 grit stone - for me it just didnt work. I am absolutely amazed by the performance of Naniwa Chosera 1000 - it is veery fast and smooth also, my razor could pass HHT after it . But i have one problem. When i normally take razor to Norton 4K, it really passes HHT nicely. For example when i am just rehoning or so. But since i tested Chosera yesterday and today, one problem came up. When i can get HHT at 1K Chosera, i start to work on 4 K Norton and i just feel the edge degrades. It shaves armhair worse and also no HHT, just sometimes in some spots on the blade. Maybe this particular razor doesnt like Norton 4K, but the 4K feels also a lot more gritty than chosera - my Norton 4K is lapped well and before i was getting good results. Now the razor barely passed the HHT after finisher and it is not sharpened well. I dont know what might be the case but i feel like the edge degrades at 4K Norton. Any ideas what this might be? I will try on more razors later, but this really confuses me. I tried to set bevel on this on chosera and move to 4K at least 4 times and still the same.
Thanks a lot.

I'm sure the experts will chime in here but I'm thinking that too much pressure may be your problem?

I really was light on it ... 1 K the razor passes HHT, after only about 10 strokes on 4 k with only the weight of the blade, razor stops passing HHT and it seems to shave hair worse. I tried also circles and a lot of other things on 4 K, but doesnt seem to help. As i say, i didnt have this problem before- i was able to pop hairs easily after 4K

I would not worry about it yet. The 1k is the bevel setter and the 4k is an intermediate hone for sharpening. Obviously you are not going to stop at 4k so go ahead and go up your progression whatever it is.

I cannot cut any of my hair until after I strop so I don't use any hair as an intermediate honing assessment. I used to think that was because I sucked at honing. Eventually I discovered that it was just the nature of my hair.

In your case, it is not that uncommon for hair cutting to be lost at an intermediate grit. You may be popping hairs after the 1k not because the blade is particularly sharp but instead because you have a sawtooth effect on the edge that is catching and then popping the hairs. With refinement of the edge with the 4k the teeth may be reduced (as they should be) to an extent that they no longer catch the hair. What you are perceiving as a regression in the sharpness is likely to be the opposite, so just keep on honing with whatever normally follows your 4k.

Thank you ... I was just disappointed because other honings worked like i said with positive HHT all the way from 4000 and now not, so i wanted to know if it has to do something with Naniwa. The finished edge didnt seem very sharp so thats what i didmt like the most.
Thank you a lot.

The hht is a very subjective test .. I wouldn't go crazy worrying about the hht. The norton 4 k is a great stone.. The true test in a nice edge is the shave test.. I really don't test my hht anymore but when I do I do it after stropping..

It is possible that you don't quite have the bevel fully set. The only thing you have changed is your bevel setter. You are used to the result you get off of the 4k, but a new bevel setter preceded it. If you don't get a good shave off of that razor, you might want to drop all the way back down to the Chosera 1k again.

Thank you, i will experiment with it and let you know ... or i can post some photos from microscope when i will hone some next razor. You are probably right, because after chosera the edge was toothier than after Norton 4k.

If you are using hair to establish a complete bevel set, you are getting a false positive. Your bevel is probably not set, as said.

Get some magnification and look straight down on the edge, if you see shinny spots, the bevels are not meeting…the bevel is not set.

Both a Norton and Chosera will set a bevel equally well, the difference is how they feel and possibly the speed, but performance should be the same.

Use pressure with a 1k, moderate pressure with the 4k and lite pressure with an 8K, weight of blade with finisher.

All you are doing with the 4k is removing the 1k stria and straightening the edge. If you are re-honing you should easily be able to re-set the bevel on a 4K.

Did you remove all the 1K stria on the 4k and are the bevels meeting?

It seems i did removed them i use microscope for magnification and tracking my process or for fast control 42x loupe... No shining or other things. I forgot to mention that this razor was a restore, but i was pretty sure the bevel is set. I might try to reset it on dmt 600 just to make sure . I may try to take some pictures through microscope and post them here.
