Morphology

sheath + knife

The meaning 'a knife carried in a sheath' is directly and compositionally derived from 'sheath' (a protective cover) + 'knife' (cutting implement); the noun-noun compound transparently describes the object. This is a common, cross-linguistic compounding pattern and a B1 learner who knows both words would readily infer the MWE's meaning.

Etymology

Sheath knife comes from the simple image of a knife kept in a sheath, a cover that hangs on a belt. Because the blade stays inside the sheath, it 'protects' the person and keeps the knife easy to carry and reach, so the term means a knife with a fixed blade carried in its sheath.
