Ok this is a little weird.. I am left handed for most things, writing, eating, cooking, reading (i hold the book with my left hand) BUT!!!! My right hand is my dominant hand when I sign. Kinda weird isnt it?
And just so you know, there is a reason people cant cut with their left hand.. Normal scissors are made for right handed people, if used with the left hand, they dont cut well and seem to just press down on the paper. But so many lefties are used to using their right hand with scissors, that left handed scissors are hard to find.
Also, a few years ago the Mall of America had a "lefty" kiosk. They sold things for left handed people, like notebooks and scissors. Other things were for decor, pencils, mugs, etc. The lefty notebooks were cool, the spiral was on the right side, but the margins and hole punch were on the left side
I bought 2 (they were kind of expensive, and I was like, 12 years old) but they later went out of business
