But that sharpener has whittled his chef knife down to a petty knife!!
Not really, I use the small Zwilling for about 30 years, but that fancy Dick Rapid device was only for testing, works well for people not interested to learn sharpening.
The knife has lost maybe 1mm in 30 years, sharpend with lots of different things, but with 1k once a year and fine steeling works pretty well, even my wife was not able to destroy it
