Shouted myself this. Got it from Sydney tools in chch link below.
Got my favourite pocket knife razor sharp in a couple of minutes at a 20° angle. Next knife was a cheap kitchen knife blunt as a piece of 4 by 2! Played around and found that 25° angle matched it good and it cleaned up and sharpened perfectly. I thought it was a bit flimsy at first but I'm slowly getting the hang of using it and so far brilliant. Will slowly sharpen everything in sight....
