Thumbport II 

The Thumbport II is a great little tool to help with tension of the right hand and combines the ideas of the original model with a new smaller overall construction. The Thumbport II has a lower default angle for the thumb than the standard Thumbport, and is also a little thicker and more rigid. The Thumbport II has less contact with the Flute and its extension arm is a little shorter.  Also, the end of the extension has a slightly more rounded shape.

If the default angle on the Thumbport II (where the back top end pushes against the flute rib) is too low, one can use a blade to cut a smidge off the end.  Be careful ~ once the material is cut, it can't be put back!
