I cut A LOT of fabric for my business and I use a combination of fabric scissors and rotary cutter. I didn't realize how dull my Rotary blade had become until I swapped it out. these blades fit my Fiskars rotary tool perfectly, I suppose how long they stay sharp would depend on the material, how many meters you cut and your cutting surface.
