Its a very simple skill to learn once you realise how to do it. My workmate is the best at sharpening knives. He's a chef and uses japanese stones.
Knife sharpening is sort of my 'house present' when I stay with people.
So often their lovely kitchen knives are 'blunt enough to ride to Edinburgh', as my Mum used to say, and thus very dangerous. I can usually borrow an oilstone from somewhere and sharpen the lot in an hour - something I learnt to do when I worked in a butchers as my Saturday job while at school.
At home I've two Japanese double stones (coarse/med and med/fine) and use a ceramic 'steel' in between proper sharpenings so my knives do tend to scalpel-like. The only accident we've ever had was when a guy dropped a boning knife he was abusing
and then tried to catch it* 
You never do that - just jump backwards fast.
