Second generation of BUCK 110 sheaths were produced from 1967 to 1969 by Atchison Leather of Atchison, Kansas.

They were made of a thicker leather.  This unique version has 2 large dimple belt loop rivets and 2 small joining rivets.

The flap has BUCK stamped on it, but not on the snap.  Also, a large 110 is stamped on the rear belt loop.
