Not sure about the problem with you shears, I don’t have this
problem with mine.
As to the saw cuts, I can think of two things that may be happening.
- You may be holding the sheet too hard, and this can cause
cramping, and 2) Your bench pin may be too low.
I found the above two reasons were causing my hands to cramp up, and
numbing the tips of the fingers gripping the sheet.
The solutions are fairly simple, don’t grip so hard, and either
raise your pin or lower your seat.
