Is a 'knife grinder' the same as a 'knife sharpener'?

They are very close synonyms. 'Knife grinder' often specifically implies the use of a grinding wheel and has a more historical/concrete feel. 'Knife sharpener' is a more general, modern term for both the person and various types of sharpening tools.

Is this a common job today?

No, as a distinct, itinerant trade it is largely obsolete in developed countries. The service still exists but is typically provided by stationary specialists in markets or shops, or via modern sharpening devices.

Can 'knife grinder' refer to an object?

Yes, it can refer to the machine or device used for grinding knives (e.g., 'an electric knife grinder'), though 'knife sharpener' is more common for consumer devices.

What is the plural form?

The standard plural is 'knife grinders'. The word 'knife' remains singular in the compound.

My Flashcards

Definition

Meaning

A person whose trade is sharpening knives and other cutting tools using a grinding wheel.

A travelling tradesperson who would historically go from house to house or market to market offering knife-sharpening services, often using a foot-powered grinding wheel. Also refers to the machine or device used for grinding knives.

Linguistics

Semantic Notes

Primarily a compound noun. The concept is more historical or niche in modern contexts, as household knife sharpening is now often done with home devices or in specialized shops. Can be used metonymically for the machine itself.
