Atoma Diamond Sharpening Plates 

Amazon sells them for waaay cheaper... $70 for the 400 grit and $75 for 1200 grit... Also you can buy sheets of the stuff for cheap, comes with the adhesive... I have double sided atomas, you can get it at tools from Japan... Hope that helps brotha

I prefer the Trend diamond stone which is a very high-quality product and has a double-sided 300/1000 grit for about $100. Both sides sharpen great! Dishing on a Waterstone isn't a problem if you spend 30 seconds flattening your Waterstones​ when necessary.

I think you're overpaying i paid like 85 euro for a 1200 plate you can get it probably even cheaper at your location, and only 17 euro for a stone holder that has 2 long screw threads instead of one.

I bought DMT extra fine 1200 grit from Amazon for 40 euro and DMT fine/coarse combination stone for 60 euro ,Both of them are 6 inch

Great informative video

Do those plates last a long time?

You should use your strop to maintain the edge of your knives.

Import everything yourself, works out cheaper. Hell im in the UK and import dmt stones from USA amazon and they are $50 there. You guys get dmt the cheapest so why buy japan ones for near $100 anyway. that is a waste of money
