Being the fact that I am left handed and was taught in the right handed world, I don't think I would be able to use a real left handed machine. Like they say, you can't teach an ole dog new tricks.
I have tried left handed shears, no luck, left handed cutters, no luck, left handed rulers, no luck, left handed ball gloves, no luck, and ever left handed golf clubs, no luck. Go figure.
Growing up in the late 50's and early 60's, it was considered out of place to be a lefty, and, everyone, including teachers, tried everything to get you to use the right hand. Nothing worked for me, I liked being the different one in class, so, I either learned to cope, or do without.
Still learning and still love being a true lefty.
