We're all different in here and it shows with replies on this thread. Hide it or not views. I'm always of the opinion that sharps need to be put away when not needed, however that should be somewhere you can easily reach it when needed for a job.
I'm kind of obsessive with my rucksack packing. Everything has its place. I'm so obsessive that I could tell someone where to find something of mine such that they'd go straight to it in my pack. Kind of precise like main compartment, to the be front 3/4 down to the left in a bit as your looking at the front of the sack ( front of sack has always been the opposite side to the harness in my mind BTW). One hand down the front of the sack without looking and you have it. That's why I'm my case inside the pack isn't much slower to reach than strapped to the outside. With the added benefit of not being obvious.
