Re-dressing Lansky diamond hones?

[Deep13]

I received a set of Lansky sharpening hones with the angle control the other day. I opted for the diamond model rather than the Arkansas hones because they were supposed to be better for some very hard steels and I plan to acquire some. Anyway, I had one knife that was really screwed up and spent quite a bit of time on it. By the time I was done, the extra course and medium grits were worn smooth like a polished metallic surface. I followed the instructions. Actually, the fine stone in now rougher than either the medium or the extra course.

The question, therefore, is how do I redress those stones so they are rought again. Lansky's website is no help.

The Diamond hones are SUPPOSED to get better the more one uses them. I myself question this but I havent had diamond hones go bad to the exstreme you say yours has. Every thing wears out, period.
Did you use any oil? Perhaps excessive pressure?

Im not to fond of that landsky for the price but I had the stone version, I didnt like how it worked and didnt like the stones that came with it. Ended up just giving it away, If the diamond hones were of the quality of thier stone version Im not terribly suprised they gave out so fast.

As for redressing, there isnt much you can do unless you happen to have a bunch of diamond particles laying around...

There are 2 articles on my website under link section I wrote, I dont mention the perticulars on what to use to sharpen but the "why" of sharpening and maintaining a edge. High Country Knives

One thing Id like to ask you is, Was your blade so old and dulled that it needed the the edge reground, I have very rarely seen a need for course and medium stone work on a blade unless it had a damaged edge other then that the fine hone, which the one you have should be about a 600 grit (most fine diamons hones are 600 grit) should have been all you needed to use to bring a toothy working edge to life, Hit it with ceramic sticks or better a solid backed strop charged with a polishing compound and done. Anything below 600 grit is not sharpening but grinding the secondary bevel, not needed for honing.

I certainly used oil and frequently wiped it off and replaced it. I suppose I may have used excessive pressure.
The inch or so from the tip down was ground to the wrong angle. It is an old Cold Steel SRK from the 1980s. The last owner droped it and broke the very tip off. He reground it, but at way too steep of an angle. To the degree possible, I was trying to correct that.
If I can't just fix the two hones, I may just replace the medium one. As you say, the extra coarse is not something I expect to need again.

If you still need to reset the secondary angle , try using a new single cut file, then go to course, med, ectect. Should save some wear on the hones if you ever need to do so again.
