When I was 11, my friend and I were sitting on the front porch swing. His Razor scooter was laying in the front yard, next to the sidewalk. The neighborhood bullies, who were about 3-4 years older than me, were walking by and randomly decided to steal it. Fortunately, I was a really fast runner and caught up to them before they could go twenty feet. Fortunately, they got scared and the one carrying the scooter dropped it and took off. Unfortunately, I was going too fast and literally stepped on the edge, the fourth toe on my left foot taking most of my weight.
Despite it really not hurting all that badly, the wound went almost to the bone and didn't stop bleeding for about an hour. For days, I could barely walk for fear of reopening it, and months later, I accidentally did reopen it by stepping on the edge of my sandal. I really probably should have gotten stitches, but surprisingly it didn't even leave a scar.
tl;dr Found out exactly why they call them Razor scooters, by stepping on one.
