Live near a farm supply store? Those fancy super thin seam rippers that are a curved blade are a knock off of a blade and handle farmers use to castrate little boy pigs. You are paying more $ because it says quilt. Just be very careful cuz they are surgical sharp. But if I have a lot of ripping to do it's my go to tool. Suppose you can tell I'm a farmers wife and worked in the farrowing house when we raised hogs.
