I only used the Nylon sheaths and now the Molle ones and so far haven't had any issues. That's not good for one day usage with that sheath. I don't recall reading of any problems with the belt area on the leather sheaths. I'd say lemon and wonder will Leatherman replace it?
I received an email reply from a Leatherman rep today, and they've offered to replace the sheath. I requested they send a nylon model instead of just replacing it with the same one. Nothing more to report at this time.
So it's been four days since my last contact with them, and today I received a package from Leatherman Looks like they were cool with my request for a nylon replacement;(Image removed from quote.)This sheath seems better overall; it has the pliers mode slot on bottom and more room in the accessory storage elastics. Time will tell whether it's more durable, but I have more faith in nylon than bonded leather.
