1. Name of object: Club with Knobs 
2. Date and country of manufacture: 2000, Hong Kong 
3. Owner's name: Sheila Butler

The Club with Knobs reminds me of A.A. Milne's poem about Bad Sir Brian Botany: 

Sir Brian had a battleaxe with great big knobs on; 

He went among the villagers and blipped them on the head. 

Take that! - and that! - and that!"

The manufacturer's directions printed on the Club include the cryptic comment: "Do not heavy to attack head and body."
