Well mines from a screw gun . Right thumb is like a light switch . Click it's up ... click it's down . No in between , and yes It does click . Hurts so bad .the one that held the hammer for so many years takes a hour to be able to make a fist after I get out of bed.
One question ,,, I went back to the first post to get the recipe . Just wondering ,,, when does the ball peen hammer get used ?
