Review on Klein Tools 5139B Zipper Bag - Cordura Nylon Tool Pouch with Heavy-Duty Zipper Close - 12-1/2-Inch, Black by Rick Turner

It's nice to keep small tools or parts assembled so I don't have to rummage through the bottom of my tool bag. I find the zipper is smoother on this 5139B than the canvas 5139. Both are great bags, canvas is a great option although the light color does show oily fingerprints. Canvas 5139's zipper feels a little heavier but is also a little stiffer. A small amount of wax would probably smooth out the action, although it's fairly functional. The zip on this 5139B is smoother, I would say it's comparable to the zip you get on a quality fleece jacket, while the zip on a canvas bag is a bit jagged as I find the jags are larger.
