Mike,

Thanks a lot for sharing this information. I use a pair of scissors that are shaped very similiar to the way you have yours. I do not know what the model is, but, they are made by Anvil and already have the off-set thumb hole made. The handles are covered with a blue color vinyl coating. You can adjust the openings of the thumb and finger holes to accommodate the different size thumbs/fingers. I will use your information to sharpen mine when needed.

Thanks again, for sharing...
