Determine grit of waterstones
I have two waterstones that I bought ages ago and have used on a regular basis. I can only describe them as "pink" softer and coarser and "yellow" harder and finer. Is there anyway to determine what grit they might represent. I would like a stone or two to fill in the gaps between.

No idea on how you test courseness, but if they are following the colour scheme used by shapton then yellow maybe 1000 grit and pink maybe 5000 grit.
If that is the case you wouldn't need an intermediate stone.

Great puzzle!I'd assemble every grit of fine sandpaper that I own (up to 3M 2500 grit wet&dry)Next, a steel scrap, soft enough to sharpen easily. I know, we all have one somewhere.I confess that I'd likely use some off-brand wood carving tool.I need my 15X loop magnifier and I need a really bright little LED light. At least 15W. CREE make good ones.The game is to compare magnified scratch patterns after maybe 20 strokes on each abrasive.I've done that at the other end, to identify 60/80/120/220/320 oil stones that had no labels.The usual cheap but unlabeled stones from the local hardware store.I know exactly what I bought.
