My sister cut with xacto knife, nearly cut thumb off! I go with her get stitches. Yuck.
Same thing happened to my index finger...still have a very bad scar from it, blood was everywhere!....Xacto knives are so super sharp and dangerous! After that very bad cut, I did not want to be a graphic artist after that.
Hope ur sister will feel better in a few days.
My students are studying cells so I need a volunteer to get their finger cut so we can see your blood cells through a microscope. Any takers using these knives? Lol
