Ambi-dextrous to a degree (like my father and grandfather).
There are many complex tasks I can perform equally well with both arms/hands (firing a gun, preparing food, mechanics, soldering, dining).
I know I'm ambidextrous by genetics though because when I went to camp to learn archery (years and years ago) the instructor found that I did not favor either eye for sighting.
Normally, the that eye you favor is opposite that of your dominant hand (right-hand, left-eyed). We repeated the test several times, but found that my aiming performance didn't change when I changed hands for drawing the string.
Further, my improvements in aiming from practice did not change at all when I swapped hands.
However, I was taught to favor my right hand for writing, so for practical/social purposes and this influence has impacted other functions (drawing, pitching a ball, using a computer mouse).
So for practical purposes, I'm right-handed, and that's what I consider myself to be openly.
I wish I had known about that earlier so I could undo the damage my schooling had inadvertently done. Oh wells.
