Have her try the knife on herself to get a feel for the pressure, sharpness, etc. Without a proper feel for any instrument the potential for harm exists. You can kill a person with a knitting needle if you try hard enough. This is an instrument *designed* to cut so she needs to have proper respect for it, and for your safety. After she gets a feel for the knife she's going to have to get a feel for it's effect on you. The sharpness of the blade matters, but so does your skin, it's thickness, texture, elasticity, etc. If you have rough skin the blade is going to catch more. If your skin is really elastic it will stretch more without cutting. For example, I have rough leathery skin. It's hard to cut, but the blades catch a lot on it. So a point is going to cut me more often than the edge. You also have to pay attention to things like scars, stretch marks, moles, and anything that causes an irregularity in skin. They all respond differently. If she's scraping the edge and not paying attention you could get a mole taken off, or god knows what. The blade can catch and skip. Then you get gouged again. Short version : he's got to pay attention to your skin, or you'll get hurt. The shape of the blade matters too. Flat won't cut as easy as curved. Curved won't cut as easy as cerrated. There are also a lot of different edges that can be on the "dull" side of the blade. Sawback, toothback, flat back, etc. Each makes for different problems - as a beginner - best to leave them be. Except flat back, that's pretty safe :))
