My two longest knives both have 7 1/2" blades but their stag handles fold over the back half of the blade. Their sheaths fit them folded. I bought two mostly because they are different designs from different makers. Only one has a swing guard and they have different locking mechanisms. I bought them in Germany in 1972 as souvenirs and collector items. While I did take them on hunting and back packing trips they are mostly novelties. The only place I recall using them opened up was the kitchen.
