I have done all cutting with a 45mm blade for years thinking "why would I need more?" I recently purchased this smaller cutter, it made a recent 'fussy cutting' experience so much easier. When the pieces are small, the larger blade was hard to control, this made it possible to waste less fabric. Looking forward to using the little one for more fussy cutting and trimming 1/2 square triangles.
I now realize why sewists and quilters use this! So much easier and precise than scissors. Love it!
