Thread: Razor eating into hone

How did you try to "re-lap" your DMT? Do you you mean running a chisel blade over it?

I assume the only way you need to worry is if it leaves scratches in either your hone you are using it to lap or your blade if you are using it to set a bevel. Have you seen any of that yet? If the scratch is just a region without any diamonds, I'd guess it will be fine. If the scratch caused diamonds to come up from the substrate, odds are those diamonds will fall out soon.

Excuse me, but I believe leaving a natural stone submerged would be bad for the stone, after all the stone itself is usually sedimentary and being so it is just some variation of compressed mud.

@ Randy.

You say you have noticed no ill effects. Is there any effect?

to be clear I have neither norton nor chinese 12. Permenant soaking may be within the users guidelines for norton, I don't recall. From soaking king stones continiously they seemed to breakdown more rapidly, but it could have been my imagination.

I cant imagine any ill occuring with a submerged novaculite, however some stones with water acting as a solvent, loosing the bond between binder and abrasive, not to mention potential chemical reaction from acidic water- drying the stone may not undo the damage... potential damage

I just read at nortons website that they don't recomend storing the 4000\8000 submerged, because of the risk of loosing the bond between them.

My Norton hones are single grit hones so I do not need to be careful of any bond between 2 stones. I would not store a 2 grit hone in water. So far I have not seen or felt any change in the Norton 1000, 4000 or 8000 nor in the Ch12K. I do not soak the Coticules, Eschers ,Tam O Shanter or natural Japanese stones.
I also add a about 1 spoon of Chlorox type stuff to the water to kill any bacteria that grows slime on the stones.

I should also add that my hones are stored in water most of the time but not all the time. Currently they have been dry an unused for about the past 2-3 months. When I start honing again after Xmas they back into the water they will go!

I don't think it's common practice to submerge hones any longer. Some Japanese synthetic hones, used to come with warnings not to keep the finer hones wet any longer than an hour, because the would break down.

I hate it that i said "imagine" twice and so close together.

I have similar issue with 12k hone. I don't know where it comes from. When i hone on 8k i get very good results and have good shaves. But when i try to polish the edge on 12k (after honing on 8k) it seems it dulls the edge (or does nothing to it at all). Maybe my techique needs more work but i've tried to finish the edge on this 12k for 2 months now without effect.

I know it really sucks.I have grown tired of this hone.Can't wait to get my shapton 16k...

How many laps are you performing on the 12K? Should be more than 50.
I use 100 laps. Also, have you refreshed the surface of the hone before lapping? When I lightly lap my 12K just before honing it cuts much better.
