CATRAHONE Diamond Power Knife Sharpener
I bought one of these little beauties a couple of years ago. Not cheap though...
They put an almost razor edge on knives and because the system does not heat up the steel, the edge stays longer.
I was taught how to sharpen a knife by my uncle who, before he went farming was a meat worker...or Freezing Worker as we call them.
Used to stone the blade to get a decent edge and then 'steel' it to align the blade and knock any rough edges off. A lot of shagging around though.
This thing does it in no time and the results are fantastic.
Made in Sheffield, UK. There is no shitty workmanship in this little bugger.
