This is a new old stock, genuine Buck leather sheath. It is made for the rubber and wood handle original model 123, but it will work great for any knife that fits into it. (also works for the new Cabelas 123 and 126, although these have thin handles. You might have to wet form the leather). We have provided dimensions to help you determine whether your knife will fit. Does have the protective plastic insert. Overall Size: 10" tall x 2 1/4" wide (at widest point). Possible blade size: 5/8" x 6 1/4". Possible handle diameter: approx. 1"
