Knife sharpening in UK

I don't know how many sharpeners and stones I have laying about but the Spyderco Sharpmaker is first rate... for some knives, but not all.

Agreed. For the money and with its limitations in mind, there's nothing better. If you want matter to faint with fear of your edges, you might need something a little finer, but that level of intimidation is very, very expensive.
