Thread: The Mysterious Missing Slivers of Edge

I would love to know the Rockwell of that razor. Could it be under hardened and just cant hold an edge????

Looks like that 5k is cracked up~! From soaking? This happened both times after that 5k was used??
No soaky the nanis!! Might have something to do with it?

Bill. Been reading here and looking at that pic of the 5k. The hone does not look good. Also, in going from 5k to12k is a pretty extreme leap, IMO. Could be a possibility that, having no grits in between, you are overdoing the 3 and/or 5k and wire-edging the thing in hopes of it being good enough to finish hone? ( I did not just say 4/8 Norton. Don't put words in my mouth! )

I have seen the beginnings of crazing on the chosera 5k - just hairlines and the merest suggestion of crazing. It has no effect on the razors I put over it, and I hone a multitude of razors.

I also have the chosera 10k, and it has the same sort of crazing your 5k has. I sent the 1st one back after it crazed like that, and got the same sort of crap from tbe vendor that he would ask naniwa about it. I put him straight good, telling him I bought it from him, not naniwa, and I wanted redress from him - that got a new 10k winging to me.

Anyway, that soon showed signs of crazing and now, after 18 months or more, it resembles your 5k.

I lap it before use, and it always does it job well, just as it should. I alternate hones a lot and have noticed that if I do not use the 10k for a week or two that the edges of the 'scales' produced by the crazing seem to stand proud by a minimal amount, but a short bout of lapping soon sets matters aright.

If you think it is the edges of the 'scales' doing the damage, try lapping before you use the hone. You could also try leaving a thin slurry from lapping on the hone, it makes a lot of difference sometimes.

PS: forgot to add that I never soak choseras, nor even submerge tnem for a short length of time.

Would that crazing produce these sliver issues, or is is two separate problems?

Thanks Neil,
I actually lap before and after honing and leave the slurry on the hone after the lapping before honing. Reason says this is user error. I will forge ahead. Thanks everyone for the info....

Well. There's that! So, Neil, what about a hone in between. Not trying to shave off a 5k and final polish on the 12k? Just moving off the 5k (freshly flattened) onto an in-between grit. Do you think it has been on the 5k too long causing this? Or could it be the 'scales' of which you speak, remedied by flattening before use? We are over LAPPING posts! HAR!

Darl, at this point I think Tom might be on to something...dang, I might have to buy another hone.....har! Like that bothers me!

I expect it could. The crazing often leaves scale-like areas like you see on the surface of dried clay in the summer, and the edges of these scales are often raised.

So I suppose if you did not lap the affected hone and the bevel (quite refined by 5k and therefore fragile) hit a raised area, then it might well chip.

As always, there is one way to find out...
