Well it looks like you wont have to trim that finger nail anymore.
I wish I had fresh pics of the scar on my leg from when it happened. Last year at work I got nicked by a diamond wheel on a grinder. It went about an inch deep and opened up about 3 inches wide. I could see my muscle flexing. Luckily the diamond wheel only burned its way through my flesh so there wasnt much blood. Heres how the scar looks now after 7 staples outside and idk how many inside.
Good luck with your finger.
