Thread: norton 4000 gritty and rough

Hello,

I have exactly the same problem.

Aaron,

One more thought, if you haven't already contacted Norton: Did you round the edges of the hone? Sometimes lapping will leave a really sharp edge on the hone, and a less-than-perfect stroke will drag the razor along the edge of the hone, giving a gritty sensation.

Or you might have a defective hone.

I did round the edges of the hone.
Josh, do you have the phone number for who to call?

The last couple Nortons I have had required significant lapping to get past the course rough feeling on the 4K side. It should feel smooth, but not quite a glassy as the 8K side.

Mine will get a bit "gummy" and bumps, but if I scrub it good under running water, this goes away. My stone is still relatively new and I will probably lap it again soon.

Thanks for the replies.
I'll try lapping it again, one more shot, but the grit does not go away, no matter how hard I scrub it with my hands, or a scouring pad.
lynn, would the course rough feeling you describe damage a razor? and how much lapping are you talking about initially? I've spent well over 1 hour combined with the 4k side on some sort of sand paper.

Hello,

I solved the problem by "breaking in" the stone using an old kitchen knife. This removed the gritty particles. Then I lapped it. The stone is now ready for use.

Pierre

So, I took a pair of large garden shears to the 4000 side of the hone, and I have a nice sharp pair of shears, plus the "embedded grit/pebbles" seem to be gone. I lapped on 220 and 400 grit wet/dry, and the 4k side is rough but no longer catches my blade. Well, at least for now this seems to have helped and I have been able to get a damaged wapi to carry a nice sharp blade.

thanks for the replies, I'll post back if I remain to have any problems.

Good deal. That's a great trick, actually. I used a similar approach to break in my DMTs, but it didn't occur to me that heavy-handed grinding might fix this problem as well.

Let us know how it works long-term.

Josh

You just have to lap deeper. No big problem.
