Along with easier cleanup and protection against possible infection, the surgical gloves give me better control of my knife when the handle gets wet and slickery. There are a lot of good reasons to use them and very few reasons to not use them.

Allergic reaction to latex is the only good reason to not use them andthen they've got poly gloves for those folks who are allergic.

They're cheap and really handy for doing chores around the house too - painting, staining and such. I've always got a box on hand anyway.
