I would hope that the kitchen utensils would be washed after use, even
if you weren't injured with them. Your right about cheese graters
though, they are definitely evil. Mine seems to take great pleasure in
removing skin and nails when used. I now use a cheese grater that has a
crank on it that keeps me away from the blades while in use. As far as
kitchen knives, it is usually while cleaning them that I tend to cut
myself. I'm married to a nurse that had many accidental punctures during
the 80's and early 90's, thank fully she never contracted anything from
them. In the kitchen she is about as clumsy as I am, but we usually
don't injure ourselves with the same utensil during a short time span.
There were times early in our relationship that we even shared a
toothbrush from time to time. BTW, we have now been married for over 20
years with three kids and more than our share of accidents involving
blood and I'm still the only one with Hep-C. I'm not saying that any one
of these could not be a way of spreading hep-c, but the odds don't seem
to be that great.

If you do happen to be as clumsy as my family seems to be, you may
consider take-out and avoid sharp objects. Hep-c isn't the only thing
that can be hazardous to your health. :)
