Cleaner in the sense you don’t have the whetstones forming a slurry on top while sharpening as cheap stones tend to do. A slightly damp paper towel will clean off any metal shavings if the diamond stone is used dry. I don’t think this is a problem with high quality whetstones.
I have two DMT diamond stones in coarse and fine. They both do the trick and can be run wet or dry. I also have a set of cheap Chinese “whetstones” from Amazon. Gotta say that both sets are able to sharpen my knives. The diamond stones I find way easier to use and a lot cleaner.
Pilots aren’t paid to manually fly the aircraft from A to B. They’re paid to handle emergencies and abnormal situations. The kind of situations that automated systems are extremely poor at handling.
I’ve been paying for proton mail for a couple years now. Decided to stick with Bitwarden when proton announced their password manager as I liked it more. Based on this fiasco I gave it a second look and so far I’ve been liking it. I haven’t committed to abandoning Bitwarden, but I’m certainly on track to.
