I agree that the scales are pretty durable and don't really need to be protected. They get scuffed up in the pocket, but don't break unless you drop it on concrete or something like that. Victorinox makes an Alox Classic, if you cared to go that route. They also make a small pocket sheath for those 58mm (Classic sized) tools. And you might be able to make or find on eBay a kydex keychain sheath.
