I use to shoe horses when I was younger and I had to have a left handed hoof knife, other than that all the tools were the same for that profession.
I guess the majority of product designers must be right handed or the review committees for new products must just see it from a numbers perspective when it comes to product sales, just not enough lefties to warrant the time and expense in a lot of cases.
Thanks for dropping by and hope to see you around again soon.
