Meaning and Definition

A fixed-blade knife designed to be carried in a sheath, typically used for outdoor, survival, or utility purposes.

A general term for a practical knife, often with a single-edged blade, associated with outdoor activities like camping, hunting, and bushcraft, rather than combat. The 'sheath' is an integral part of the concept, distinguishing it from folding or pocket knives.

Dialectal Variation

British vs American Usage

Differences

More common in British English, where it's a standard term. In American English, 'fixed-blade knife' or simply 'hunting knife'/'camp knife' is often preferred, though 'sheath knife' is perfectly understood.

Connotations

In both varieties, it suggests a tool, not a weapon. In British English, it may sound slightly old-fashioned or traditional.

Frequency

Low frequency in everyday language for both, but higher in specific communities (e.g., scouts, survivalists). More likely to be encountered in British outdoor writing.
