Recently I screwed up my Cruwear Delica cutting aquarium plants not realizing they have wire in them.
This caused some pretty good plastic deformation of the blade but no chips.
To repair this I put it on the WEP3 but went conservative at 15 DPS. Started at 600 Grit which works great for Cruwear no need to go lower, and finished at .5 microns.
This knife now cuts better than when it was new out of the box. It constantly amazes me how much more I can get out of any blade with this sharpener. I am talking push cutting telephone book paper without snags sharp!
After reading what ViVi wrote I think I am going to try to get this one down to 10 Degrees if I can finagle the low angle adapter just right.
Despite all the free advertisement I seem to be doing I do not recommend this sharpener it is far to expensive and requires too many overpriced add ones to get into the really low angles, ouch expensive rabbit hole this one!
It does work precisely though
