Hey Mitch, I am a total ambidextrous mess. I also grew up playing all types of sports, Baseball, Lacrosse, Tennis, Basketball, you name it. I was straight up righty, except that in Lacrosse and Baseball, I could bat and throw lefty as well. I also grew up wanting to shoot guns and shot pellet guns occasionally. Now, once I got to about 20 yrs old, I got to take a rifle class in College Phys ed. I started out righty but experienced targets that would blur on me as I aimed with open sights. I asked the instructor if he knew why, and he said we needed to check my dominant eye. Of course it is my left eye. I began to switch shoot from that moment on, I shot lefty in that class. I am more comfortable shooting right handed, but if I strictly shot lefty, I could do it just as easily that way too. With guitar, I naturally placed it in right handed position. Same with Golf, Fun stuff LOL.
When I operate a saw, I use either hand. Tools require hands, feet, eyes, and I joke and say sometimes ears to handle the material and tool all at same time. As I find with things like soldering, heck, I wish I were an octopus 1/2 the time. I can use my soldering iron with either hand, equally as well. Probably comes from sweating pipes either way as well.
