Ouch. Finger tips are the worst. A pain to heal/wrap up. I was sharpening an insulation knife (basically a filet knife) and am so used to it wasn’t paying attention and was looking at something else the same time. Knife slipped out of the sharpener and got the top of my thumb. Cut 1/8” through the nail and through the tip of my thumb. If I held it up it looked like a V. Just healed a couple days ago, happened about a month ago. Keep it clean!
