I use a 10 inch Mill Bastard File from the hardware store and a small honing stone. Once in a while I will pull out the steel in the kitchen but not very often.
I think sharpening stuff is a learned skill--you have to work at it a little, pay attention to what you're doing, take your time, and the skill will come.
I can sharpen the Wensels, or Snuffers, or even 4 blade Zwickey Deltas with no problem, and in very short order. JKust keep on working at it and before long, you'll be doing it too.
