At home we don't cut with the antiques of course (I could never bring myself to do that with my precious nihonto personally), but we do have our favorite blades for cutting and form work. Mine is my customized Hanwei Shinto (which I can authoritatively say cuts a LOT like a nihonto now that I have been able to cut with a genuine nihonto in proper polish), and her favorite is the Kawashima Ko-katana since it suits her petite frame very well, but still has a katana tsuka.
