i had the older Veritas sharpening jig with the single brass screw on top that was OK but it did allow the plane iron or chisel to move sometimes. I bought the newer Veritas MkII sharpening jig and it worked very well except for narrow chisels. Veritas just came out with a narrow head that fits on the MkII body that works exceptionally well for narrow chisels.
The newer Japanese water stones stay flat a very long time (Shapton Glass, Shapton Pro, Nubatama Ume) to name a few that I use on a regular basis. I have a Atoma 140 grit diamond plate that I use to touch up the stones when needed.
