I recently bought the Fiskars and initially liked it but after using it to cut strips for a Judy Martin pattern, I discovered it was cutting strips about 1/8+ too wide. Between that miscalibration coupled w the flimsy acrylic handle, it's being returned.
I purchased the Havel's instead and sure enough, its cutting measurements are correct
The acrylic also seems thicker and I find it's easier for me to read.
Just my experience.
