Up until recently I have used a Lansky Kit with reasonable success.
But - have invested in a Chef’s Choice electric sharpener - which is brilliant!
I don’t think I paid as much as £160 though. It is 240v and has UK flat-pin plug fitted.

Now - all my knives have fantastic edges - passing the ‘ripe tomato test’.
