Really. They are. I mean I totally love my diamonds - they are always plane, they never need trueing, they do not need to be soaked before use, they don't even need lubricant, and they come with their non-slip feet or non-slip mat. Plus they are quite abrasive, even with small grain... so what's not to love?
For those of you who are confused: I am talking about diamond whetstones. And for those of you who ponder buying a whetstone for sharpening kitchen knives or other tools: I can totally recommend a diamond stone. They are a bit pricier than normal stone stones, but they last forever, they never develop a ditch, and they are easy to clean.
This post was brought to you by the person who finally finished sharpening a new tool (that came very, very unsharpened) and can now start to work on those 6-hole weaving tablets that are supposed to go into the shop soon...
