I have a pair of pinking shears but haven't used them in years. They're still in their original case even. Found specialty blades at Nancy's Notions and ordered them. Their pinking shears ones as well as the one to cut evenly holes in fleece when you want to tie them together using yarn. I use the pinking blade whenever I'm cutting into dress fabrics and fabrics that seem to fray alot. Love these blades. Yes, they're expensive but if you're not using them constantly its my go to blade when I need it.
