What are you trying to do? It's always best to use the right 'tool' for the job.
If I'm cutting all the way through a model (for example, at the waist for a bike conversion), I use a saw similar to the one linked (hobby store budget version, no issues for what I use it for), but without a vice or anything - just a cutting surface and a rigger glove on the hand holding the model (that way the first slip won't injure me). Patience is vital - trying to go too fast puts more pressure on the blade, and makes any slips (inevitable really) more likely to injure.
A sharp blade is less likely to hurt you. I know that sounds completely the wrong way round, but if you're having to put more force into the motion due to a worn blade, you're more likely to slip. For close-up stuff with a hobby knife, I use rubber thimbles (of the sort used for counting bank notes) to protect my digits.
I don't have much experience cutting in a curve (not strictly true - I always try to cut straight, but end up with a slight curve), but you'll need a thinner blade for it (a wide blade assists cutting straight, and attempting to 'bend' it for a curve will damage the blade and possibly break it). Again, explain what you're trying to do exactly?
