Welcome to this board.
I use 1 of 2 machines. One has a threader and thread cutter, other one doesn't have either. Both have a knee lift I never use, both have needle up/down, I could not live without that feature.
Thread cutter cuts thread about 1/2" long, not good for me when I quilt. I never remember not to use it when quilting and looks messy on the quilt back.
