I bought a Worksharp 3000 about 6 months ago and am happy with its performance. I have purchased extra sandpaper in the middle grits a few times and I am satisfied with how long they last. I am, however, a little taken back by the cost of the fine grit papers. Most discs cost $16 for 10 on amazon. The fine lapping paper is $16 for 2. While looking at the sandpaper I noticed these lapping discs that look like they were made specifically for the worksharp. They are reasonably priced, assuming they last longer than sandpaper. Does anyone have any experience with these discs?

I haven’t used these, although they do look interesting.
I’ve taken to buying the cheapest PSA sanding disks I can get (HF) for the rougher grits. They don’t last as long but do the job. For the finer grits I use mdf with honing compound (idea taken from Stumpy Nubs).
That said, the WS doesn’t get used as much since I’ve mostly switched to hollow grinding and hand honing (but the WS is really great for card scrapers).

I have one of the lapping dics. I bought mine from Amazon, but am not sure it’s that exact one. In any case, the one I have isn’t quite rigid enough to use by itself, so I mount it on top of a glass disc. I use it (mine 1000 grit, IIRC) for touching up nicks, etc. on my tools. But since it’s higher than a regular disc on a glass plate, I can’t use it in the rotation of grits I use for sharpening. I have several glass discs with different grits, and will just change them as I wotk an edge onto a tool. I have a suggestion for the finest grits: Micro Mesh. You can get them in grits up to 12000 (yep) and they are extremely well made, very heavy backing and the grit has a long life. The 12000 may be to fine for most folks, but it puts an edge on a tool that exceeds “surgical sharp”. Anyway, they run about $2 each, but they are worth it (IMHO). at least try a few and make your own judgement. Oops, should mention: they don’t come with a hole, you have to punch your own.

Hey Fred, I like that idea. Have you bought from that site? It looks like they have a $40 minimum. I am not sure if I need $40 worth of lapping discs but I really like that idea.

I have indeed, a couple of times. Yep, they do have a $40 minimum which I met a couple of times. The third time a fellow on another forum set up a group buy to make things a little easier. I also bought an “arch punch” to put holes in them, I think I paid about $10 for that, General makes the one I got.
