I can not say at what angle to resharpen it at, but after using my CU7 to chop a couple of 6" diameter trees in half, the edge held up nicely. Still able to shave some hairs after use. When I got back from my multi-day outing after using it, I just wiped down the knife and oiled the edge and no rust thus far.
As for putting the Altoids tin in the pouch, mine was the same way, hard as heck to get it in there. I finally managed to get it in by stretching the elastic strap. It's still tight to put in and out, but I'd rather have it too tight than too loose. Total contents of my pouch contain a bottle of iodine tablets (horizontally on the bottom), Altoids tin with a Bic lighter vertically to the side.
