Trail saw
I carry my saw (036) on my shoulder when clearing trails, with a Pack Shack cover over the Stihl blade guard. My gas goes into MSR bottles and my oil into an old Nalgene bottle. I put all the other stuff -- wedges, scrench, extra bar and chain, etc. into a rucksack and run an axe through the pack's loops. Prior to the Pack Shack cover, I just wrapped a square of foam around the blade guard and duct-taped it in place. Saw rides nicely on your shoulder for miles and miles. Just make sure you your gas cap is tight (how would I know that?)
Having just graduated to a 362, I'm not sure how my home-made bucking spikes will carry on my neck. The little ones that came on the 036 never got in the way (or worked very well either).
