The Simplest Tool

The simplest tool in my arsenal is a chalk line. A quick Wikipedia confirms my memory that chalk lines were used in ancient Egypt. It's really cool to think I use a tool today that probably helped with the pyramids!

What is a chalk line? It's a length of string on a roll in a metal box containing colored chalk. It easily stores in my tool pouch and in a pinch can replace many other tools. There is a high-tech replacement called that uses a "freakin' laser beam" (I'm channeling my Dr Evil here) - but that needs power and is somewhat delicate.

Here are a few of the things I use a string for on the regular:

• snapping a straight line
• as a guide to compare to another line to see how far off the other one is (like an old ceiling or floor that dips up and down).
• as a layout tool - drive a couple of nails and run the string between that and create a layout grid (you will often see brick layers do something similar)

Did the Egyptians use it for the same things? Probably. With all the advancements we've made, building still has fundamental problems that tools invented centuries ago can still solve really, really well. And now I'm humming "Walk Like an Egyptian" in my head - and you are too - you're welcome!
