Did I mention that I love Costco?
I got them at Micheals or Fabric World or one of those craft stores, which is the second best place to find totally unrelated stuff to apply to flyfishing... besides Costco!
The amount of use my fancy FF scissors get dwindles each season. I used to use them just for tough materials, but I tried them for my muddler heads and they are awesome - just squeeze and trim around, rotary vise makes it real easy. I save my fancy scissors for spey flies and trout flies.
