This oddball screwdriver is one of the most ergonomic tools I own (and it's only $15)

• The XLX 4.2V screwdriver is available on Amazon for $15.
• It features a classic design that is surprisingly ergonomic, and more than powerful enough for regular DIY tasks.
• The LED light only comes on when the screwdriver is on.

Sometimes I'm wrong. It doesn't happen often, but when it does, I try to learn from it. Take the other day, for example. I received a new screwdriver for testing, and I was initially quite dismissive of it. After all, the price was under $20, it was from a brand that didn't ring any bells, and it looked a lot like something my grandpa would have used back in the 1980s.

But I was wrong. It turned out not only to be powerful, but surprisingly ergonomic.
