I love to shave, but I hate buying replacement blades for my razor. One, they’re expensive. Two, they’re usually locked in a glass case. Here’s a trick to help you save money and avoid talking to the people at Walgreen’s:

Take your old razor and push it backward against the skin of your arm ten times (in the non-shaving direction! Do not shave your arm hair! Unless you want to!). Congratulations, your razor is now sharp. It’s worked for me–I’ve gotten a couple more shaves out of a blade I thought was done.

Here’s an instructional video. (I’m pretty sure you can do this and wear a shirt at the same time, but I’m not willing to risk it.)
