<human>: Give me the gist of the text in a nutshell

Okay, I recently went to this cool fun store in the city I live in and they had these amazing 'industrial grade' cutters on sale for less than a buck. I thought I had to have one of those and figured they might come handy every now and then. No real reason to buy them, just thought they'd be fun to use.

Today, I was testing how sharp the blade on the cutter was by trying to cut through random items in my room. Then I thought - "Hey, why not try to cut through a sandal sole?!" So I did. Except, it wasn't my sandal, but my roomies. After I was unsuccessful in cutting through, I decided that it would be a great prank to cut the side-strap of the sandal till only a little bit was left and watch my friend freak out when he wears it out one day and the strap tears due to all the friction. Well, I was caught red handed while attempting to cut through his strap. Roomie is quite pissed but I guess I'll be able to calm him down a bit.
<bot>: Was playing with a really sharp cutter, cutting things. Thought it would be funny to cut the side-strap on my roomies sandal. Got caught while doing it. Busted.
