Today I cleaned and oiled my hair clippers

Just the blades. On my clippers it's just a couple screws. (They're quite small, so be careful not to drop them, especially if you do this in the bathroom where they could go down the drain.) Remove the blades, brush them with an old toothbrush. Also brush the area around where they are installed. Finish up with a paper towel. Then reassemble, add a couple drops of clipper oil, and they're good as new.

I think this might become an annual tradition around New Year's. I've done this before, but I can't remember when or how many times.

I bought these clippers over 12 years ago. I haven't paid for a haircut since. That's saved me at least $120 a year. Over $1,000 that's still in my bank account. And cutting my own hair is more convenient. I can do it whenever I want (at midnight or early in the morning, whatever), no need to drive somewhere and wait.

I bought the clipper oil several years ago. A small bottle, a few ounces, is probably enough for a lifetime. With oiling and cleaning, these clippers have lasted a long time and helped make me more self-sufficient and saved me money.
