I can feel that my razor needs a refresh, so I'm considering buying this (mino Sharp Slipsten #1000/8000 inkl. MC462 - minoShap - Global - RoyalDesign.se) and was hoping for opinions. Sorry that it's in Swedish, but the manufacturer is "mino Sharp", and it's a 1k/8k stone.

Is this a reputable manufacturer? Are those stones too rough for refreshing a blade?

Thanks!
