If you are going to be butchering a lot at home then please invest in one of the high end Chef's Choice sharpeners.
They are the same sharpeners used these days in the professional meat packing/processing houses.
They create a flawless, highly agressive perfect edge for meat/game.
I can't begin to tell you how great they are.
Plan to spend $140.00 bucks or so.
They are absolutely fantastic.
