Messenger bags are great but sometimes the long shoulder strap gets tangled when you're trying to make a quick exit or easy entrance. Since they all seem to have a couple of 'D' rings on the back, I decided to make a quick short strap that won't get hung up on stuff as I drag it out of the car to avoid the coming zombie apocalypse. But the problem is that if it's too narrow, it's too uncomfortable to use zombies or no. So, enter the Portuguese Sinnet (also known as Solomon Bar and referenced as knot #2496 in Ashley's Book of Knots).
