For this step I have used the C-Clamp to clamp the Butter Knife to my end table. I use this instead of the stove only because the width of the metal on the stove was larger than the bend that was required. As with the stove technique I have taken my Candle Lighter and heated the knife for about 5 seconds. I set the cut Credit Card on top and bend the tabs down to what I believe to be 90 degree's.
For the second bend it goes pretty much the same as the first except this time we need to make sure that the depth of the bend matches the depth of the slot on the mouse. For this I just set the tabs in the slots and did another guesstimated measurement of the depth that it set in.
