I am glad to be back after being away for some weeks.
The answer of this week's spy game is JACKHAMMER.

From the clue given above, JACKHAMMER fits the description because:

1. It is a 10 letter word.
2. It is a compound word. Compound words are formed when two words are used together to yield a new meaning.
   Here, the word Jack and Hammer are being used together to give Jackhammer which now means a heavy duty machine used widely in construction works for jobs like breaking up concrete footings around fence posts, demolishing roads and pavements, breaking down boulders and large concrete slabs, ectera.
3. It combines two tools: Jack and Hammer.
4. Operators wear protective gears as it is adviceable to always be on protective wears and observe the necessary precautions when using machines.
