Would you recommend a particular wire cutter for .019 size, 49 strand Accu-Flex® beading wire?
I personally like the Lindstrom® flush-cutter as it cuts cleanly and gets in close to my work, leaving virtually no beading wire exposed past my crimp and it also has ergonomic handles. It is expensive, but worth it! The Lindstrom flush-cutters will last forever if you take care of them and they will never disappoint you.
If you'd like a more economical tool, the Wire nipper is a great tool and also works well when cutting Accu-Flex® Professional Quality Beading Wire.
