 The cutter is usually an older woman, but in communities where the male barber has assumed the role of health worker he will also perform FGM.When traditional cutters are involved, non-sterile devices are likely to be used, including knives, razors, scissors, glass, sharpened rocks and fingernails.According to a nurse in Uganda, quoted in 2007 in "The Lancet", a cutter would use one knife on up to 30 girls at a time.
