Step 1: What you need
I know this is very simple and to some it's worthless but I found it useful.
What you need
-Can opener (empty but whatever makes you have a better time making this)
Step 2: Taking off the top
On the first can I cut I didn't get any sharp edges due to a bad cut. But I did the second time. You can bend the sharp parts that stick out back down but I would suggest just getting a new can. You don't want to risk hurting yourself.
Step 3: Clean and finish
You can use it for whatever you like. I find it really useful to keep your pens from being all cluttered every where and it makes them easy to get to.
You can also use it as a mini trash can or even for keeping all your screws, nuts, bolts, and so on that are laying around your working area.
