The I Like Twists six piece tension tool set is primarily produced from SS flat wire. One of them is made from Gov Steel.
The benifit from this type of turning tool is that your finger's tension control is modified from 100% to a tension range. There are times when this is extreemly important such as in picking spool pins. When lifting the trapped spool (or serrated) pin from it's trapped position, a lighter tension will allow the plug to reverse the slight amout required to allow the bottom of the pin to rise above the sheer line.
Another benifit to those of us who get a little heavy handed at times is that we don't need to rest the pick on the front of the keyway and crank like crazy because our tension is too high.
Remembering from the old days: Rev the engine and pop the clutch = spinning tires and sometimes broken drive train stuff. But a balance between clutch and gas allows for a smooth start.....
Each of the six turning tools are of a unique size to allow for keyway fit and tension range choices.
They are made with a 5/8 inch bend at one end, accompanied by a 45 degree twist.
The material sizes that were bent and twisted are:
.100 X .020 X 5",
.100 X .025 X 5",
.120 X .025 X 4",
.120 X .030 X 4",
.120 X .025 X 5"
and .130 X .030 X 4"
