I need a 20+ tooth per inch, plain end, scroll saw blade. I’m making puzzles for my daughters Campfire troupe out of pictures that they made for their moms, but I don’t have any spare blades. NONE of the local hardware stores carry them, and Amazon won’t get it to me until next week. To be extra clear about the blade, I cannot use the pin end type on my particular scroll saw. The Firebird Campfire troupe thanks you!!!
