I've been persevering with the Horl and am definitely getting better results but still not up to the level I remember them after being sharpened by hand at a shop. I also find they dull much quicker than in the past so I've decided to enrol on a knife sharpening course at the Baker St JKC, will report back.
What kind of knife and what angle are you using? As I understand 15 degrees is only really suitable for harder steels HRC 60 or more, softer western blades can’t hold that kind of edge.
Also did you get the premium set? I get the impression if you want a super fine edge they are necessary.
