I think my only problem with the Classic is the key ring location. I'd probably end up getting a case like you have there so I can take it out. I also found the SD tip quite handy.
Yeah, no matter which way the keyring is put on, it's facing he wrong way. If they put it on the other end, then everytime you use the scissors, the keys are in the way. As it is, when you use the knife blade or the SD tip of the nail file, the keys are still in the way. That's one reason I made the pouch. The knife fits all the way in, so that the keyring is the only part sticking out, and I use it as a grab ring to pull the classic out of the sheath. It makes the classic more usable. Some scrap leather, some waxed linen thread, an awl, and you're in business.
