Ive shaved with straights for 14+ years and yet to have a bad bleeder (on myself) knock on wood....I cant say the same for my customers lol...I caught the heel on a customers ear a month ago while giving a head shave and it was still pouring blood 15 minutes later even with heavy pressure and styptic powder.....he pulled the tissue off before he left and blood dripped all over his shirt....he still comes in once a week though.
