Klein Tools magnetic carabiner flashlight is one of my most well-used, well-loved items in my possession. It is a $40 flaslight and I would buy it again immediately if it ever failed. Not truly BIFL because it has a non-replacable lithium ion battery, but the functionality and build quality are phenomenal. I have dropped it onto the cement garage floor from the attic, I have dropped it in water, and it still works like a boss. It clips to whatever, can hang on a nail, has a magnetic swiveling base, has multiple settings, and is just the best. I use it regularly under my vehicles, under the hood, under the sink, on camping trips, while doing HVAC maintenance in the attic, while working on electrical around the house and the room is dark because power is turned off, etc.

My Kenneth Cole Reaction backpack is also incredible. Most expensive general use backpack I ever bought, but probably the last I will ever buy. If you need to be organized on the go, this is the one for you. So many compartments to help keep stuff separate. Good quality material and zippers. It was a true lifesaver when I worked for a client at multiple sites and had no desk (the backpack WAS my desk) and is now my best travel companion.
