Oh, Ruth,
I have a permanent callous on my finger and thumb from using the pinking sheers on all the garments I've put together over the years. I can't even't file them off with an emory board. I started doing French seams to avoid the pain and the ugly lumps. They really hurt to try to use them, for me anyway. H even bought me some that were recommended by the fabric shop from Fiskars with the soft handles, but they drag anyway.
I'd forego that pain if you can!
