I use japanese waterstones to sharpen my tools. I start with my 1000x stone which works fine however when I switch to my 4000x stone that’s when I have a lot of trouble. Although I use lots of water when I’m sharpening I get a suction effect with my 4000x stones which prevents me from lapping the back of my irons smoothly. I tried making groves in my stone to prevent this but that didn’t work. I also tried using a Nagura stone which is supposed to help however I’m not even sure if I’m using that properly as well. Does anybody have any advice on how to use high grit japanese waterstones for creating a mirror finish on the back of plane irons and chisels?

How much of the back are you trying to flatten? If you do only the last 1/2 inch or so, which is all that is necessary, there is not enough surface area to create a leve.

Additionally, try using less water. Many of the higher grit stones only require a spritzing immediately before use and too much water can be a hinderance rather than a help.

We have our 1000, and 1200 stones soaking in water. As we sharpen we will wipe the stones when you can start to see a black slurry (metal shavings). Dunk your hand in water a little and wipe it clean. When we move up to our 4000 and higher get it wet and as you sharpen you have to find a happy pressure otherwise your blade may skip…..you gotta practice. I agree with jay, just polish the last 1/2” or so…..realistically youre not even using that much…..and if you have a suction problem try less water. good luck

I only polish about 1.5” on the back of the plane iron. I get
suction too if I try to lay too much of the iron on the
stone so I decided it wasn’t worth the hassle. Getting it
nice only matters right at the edge anyway.
