just wondering if anybody uses shaptons, and how well they work, especially for steel like cpm 3V. can't decide whether to go with dmt or something like shapton, i love the idea of using water as a lubricant, but don't really want to flatten a stone every few times. i know dmt are great, but are they really the best for 3v? the shaptons seem closer to the "self fulfilling" part of sharpening blades that some of you talk about, rather than just speed. please let me know what you guys use and think, i don't want to buy the wrong stone. like i said, i love the water stone thing, but not sure if any water stones will work for such a tough steel. thanks for the patience fellas.

Shapton Glasstones work great for D2 and S30V which are not as tough as 3V, but much more wear-resistant. DMT stones work, great, too.

If you want a semi-polished edge that will pushcut, but still have enough tooth for slicing, you might just want to get an extra-coarse DMT and a fine DMT. It's not as 'fun' as waterstones, but it's faster and you still get to use water (or kerosene or whatever).

Thom,
Could you explain more about sharpening for pushcuts and slicing
Thanks

Wear resistant is more difficult to sharpen. When you sharpen, you are "wearing" down steel. If it resists wear, that means more work for you (absent the proper equipment and technique).

Wear-resistant means it's less work to wash a cat.

Steels I've sharpened with Shapton Glasstones:

VG-1, VG-10, 12C27M, 13C26, INFI, S30V, 5160, 1095, 1080, S7, 52100, ZDP-189, SGPS, SG-2, D2, M2, AUS-8A, 154CM, and AEB-L.

Steels that didn't sharpen easily with Shapton Glasstones:

None.

Sure. When using edges that 15 degrees or more per side that are about 0.025" or thicker at the top of the edge, coarser edges tend to be better edge slicing and polished edges tend to be better at pushcutting. When angles get lower or are thinner behind the shoulder (such as 0.006" thin or so), then coarser edges seem slightly better at pushcutting, but not so much that I'd use them.
 
wow. I really want to get the shaptons for Christmas, and i REALLY love that they are used with a lot of water. does anyone have bad experiences with them? do these still need to be flattened like other waterstones, are they better than other waterstones? thanks for any help.
 
To the OP,
What series of Shapton stones?

I use the Shapton's Professional Series stones at work in my furniture shop. Most of my tools are A2, but I have sharpened D2 and CPM D2 on them quite a bit as well. The stones do need to be flattened periodically. How often and to what extent depends on whether you are just touching up or re-profiling. If you just need something for sharpening from time to time I would recommend something that doesn't require a lapping plate, as they can be expensive and time consuming to use. If you don’t mind spending a little extra time and energy caring for your sharpening equipment, Shapton stones are great.

I hope this is of some help.

I use the Shapton "Water Stone Correction Plate" for truing up stones. It certainly works well, but will run you over $150.

I have never tried a diamond stone for flattening, but have heard from several others that they work quite well.
 
anyone have experience with this? i hope i can do this, i need a dmt coarse stone anyway, and it would be great if this could work on the shapton 1k, 2k? what if i get 5k or 8k in the future, will it still work? thanks again for all the patience.
 
i flatten my edgepro stones on a cheap diamond stone from harbor freight. works great.

cool thanks. any grit will work for 1k and 2k stones? thanks again.

I use a coarse or the fine for those (depending on how dished it is), and fine or Xfine DMT's for finer waterstones.

You really can get an idea of wear resistance by sharpening on shapton pros - I use them for all of my knives, and they remove material from all of them, but they remove a lot less CPM-10V per pass then they do with 1095! From the feel of the waterstone and residue left on it, 10V and 90V seem to be the top of the heap in wear resistance (haven't tried 110V - yet). 90V to me is a weird feeling steel to sharpen and feel the edge - the edge has a strange feel to it even when very sharp.
