Need help with limbo of the lost

I'am in the office of woe and need to unlock the metal jaw clamp to blind setting,but it does'nt matter if I use the action icon or the hand,neither works. Briggs says he already has it. what can I do to unlock the metal jaw clamp?

Jackie,

Be sure to look close at the clamp first.
If I remember correctly you click on the joint area of the clamp. It is at the side-corner of the clamp. Then it will change.

Mag,I looked at the clamp close up and clicked everywhere,left and right side of the jaw,especially the rt.side where a clamp can be seen. I clicked all around the area and still could not get it to open. I could see the clamp and part of the fingernail and clicked all around the areas but I could not get the clamp to change to a metal blindfold.

Jackie,

Use the action icon on that square at bottom right, not just mouse click. Good luck.

Mag,after Using the action icon after looking close up at the clamp triggered the clamp to change to a blindfold. Thank you for your patience and the suggestion.

Glad you're moving forward now. Enjoy the game.
