I stabbed myself yesterday while setting the mail on my newly de-junked glass workbench. I don’t know what did it and I thought maybe a just bruised myself for a few minutes. I pierced the back of my hand an inch below where my pinky & ring finger meet. It didn’t bleed much like palms/fingers which made me nervous because I don’t want anything in my hand that was on the mystery object. The gash is about a centimeter long.
