    I can't think of when I've actually used it.

    I've seen comments about how 3, 4, 5 allows you to make a square corner with a tape measure, but I've never had an opportunity to use that trick.

    I find myself trying to guess the area of things a lot more.

    I guess your not a carpenter and you don't build things? It's super useful. I don't use it all that often but it's an excellent tool to have. Even just laying out a square garden, say. It also works with any multiple to make bigger perpendiculars, 6, 8, 10 or 15, 20, 25
