I believe that you can find some ideas on how to learn mentioned in another thread from not too long ago.I and a couple of others mentioned the methods we've used over the years.
A quick recount from my post was:
Tape the edge of a single edged knife,and use the bite handle in hand instead of the safe handle.Learn where the edge would normaly come into contact with the skin and then you can figure out how to modify the manipulation so that the edge will either miss the skin or will only drag across it (not cutting into it).You can also learn how to make sure that if the edge will need to hit the skin,how to keep it from slicing in deep.A small nick is ok,but a large one is always dreaded...so learn how to minimize the damage.
Or,you can take a double edged blade and tape both sides.Use it in the same way as the above method,but also start looking at what moves are the safest (i.e. those where neither edge will hit the flesh in a bad way) to do.
One important step is to learn how to exaggerate the wrist and/or finger movement so that you can control the physics of the movement better.If you figure out how to slow the movement of the handle and/or blade motion at the right points before sending them off into another direction,then any possible damage to you should be lessened to a good degree.
Just take your time,tape your edges,and do your best to learn where & when the edge(s) will hit,and from there you can learn to minimize the possible damage.
