The handle looks solid and well-fitted. Sheath: Brown leather with a snap-closure belt loop, darker body section, and lighter brown collar/tip.
Size: From the tape-measure photo, overall sheathed length is roughly 9.5-10 inches. These knives are typically 9-10" overall with a 4.5-5.5" blade. This matches the classic "Original Buffalo Skinner" pattern that was very popular from the 1950s through the 1970s. Most were made in Solingen, Germany by various firms Edge Brand/Gutmann, Premier Lifetime, Anton Wingen Jr.
And often came with stag or bone handles and leather sheaths (sometimes with animal embossing). Your example stands out because of the buffalo carving/etching on the handle, which ties thematically to the blade etch. Some German examples have bone or stag with decorative work; others are plainer. The construction (metal pommel, stacked spacers, curved skinner blade) is very much in that mid-century Solingen style. It is less likely to be one of the modern inexpensive Pakistani "Buffalo Bone" skinners (those usually have finger-grooved resin/bone handles and a different look).No clear maker's stamp is visible in the photos beyond the blade etch. Checking the ricasso (the flat area right above the handle) and the reverse side of the blade carefully could reveal a maker mark, model number common ones include numbers like 496, 477, etc.
