Guess the Implement - the Reveal

 This is the full view of the implement you saw in the last post. It's called a Boa Constrictor Strap Wrench and it's used to tighten or loosen odd-shaped objects. Congratulations to all those who guessed correctly!

This one is from Ron's toolbox. According to the online catalogue, it comes in two sizes "for general household or heavy-duty applications. Non-slip, soft rubber handle for a secure grip and superior comfort. Incredibly strong, but won't scratch."

This is the underside. As you can see, the useful part of this tool is the loop on the right. The excess length of rubber strap on the left is the business end for - ahem - other household uses :)

Thank you for all your clever guesses. Complete the Caption will return next week.
