I use a coarse 3m diapad for freshening up stones. Black or red. Yes they are pricy but seem to last for many years. They flex slightly so you don't have to flatten the stone to get at the whole surface.Just thought I'd send an update. I'm very much enjoying the fine India stone. It definitely took some getting used to after the diamond stone system but I'm very impressed by the edges it leaves. I always noticed that the diamond stones left a sticky sharp edge and I always assumed this was the top end of sharp. So I when I didn't get that with the fine India I started to panic a little. But when I sliced through end grain with it I was astounded. I believe now that the oilstone is leaving a smooth edge whereas the diamond was more serrated?
I am still using the extra coarse diamond stone for grinding the whole bevel and then just doing the edge with the fine India and then a charged strop. I did come across a coarse India stone for a good price so took it as a possible replacement for the diamond stone when it gets too worn. This brings me to my question of whether you guys think it's OK to use my broken in extra coarse DMT plate for conditioning the oilstone surface, given that I need it to grind my tool edges too? I have read in a couple of places that oilstones will quickly wear good quality plates, so use cheaper ones. But ideally I don't want to keep accumulating extra kit. I'm not too worried about flattening because I know the stones are hard and I am always trying to use all the surface. Just for keeping them cutting well. Cheap diamond plates seem hit and miss and the 3M diapad is fairly expensive.
Thanks again for all your advice. Really pleased so far that I made the switch!
In fact you never have to flatten the stone - a slight hollow across is good for cambering the blade and dishing along the length has no effect on anything.
You have to un-think 90% of modern sharpening practice to get back to trad freehand sharpening, but it's worth the effort - simpler, faster, cheaper, effective, stones last for life.
I did have an expensive set of Ezelap plates but sold them on
PS I don't grind thin plane blades or narrow chisels but for heavier plane blades the coarse side of a combination stone is good if you use a holder - a length of 2x1" with a slot for the blade. You can then work it fast and with pressure from both hands. Not needed for chisels of course as they have their own handles!
