Hand planes/hand boards what's in name?

You'll have to forgive me I Did the majority of my growing up a continent away. So It surprised when at the Sacred Craft Expo down in San Diego a couple weeks back most people where referring to our body surfing epoxy Boards as Hand planes. So what's in a name? hand planes, body surfing boards, Handgun there are more but you get the point. So what's the  difference! Well to be quiet blunt not a whole lot I'm not particularly fond of the Name handplane or handplanes. which would probably be the reason I like to use Handboards, Not that there is anything wrong with the Handplanes name I guess it's just a personal preference.  In fact  if I had it my way I would call them Handguns which is what we used to call everything and anything you used as a board for body surfing when  I was a kid .  10 points to the first to guess why that probably wouldn't be a great name idea.  In fact  our Fed ex guy Timo: a super cool Samoan /American man mountain  walked  into  our office space and immediately inquired about the sweet handguns. So apparently as he grew up in Hawaii that's what they call them there too.  So  really it's more about what you're used to or grew up with than any hard fast rule think we will stick with Handboards thing. I like the reference to board in it I guess it reminds me of surfboard more and really they are intrinsically  intertwined as water sports.  One thing is for sure body surfing came first and who knows what would have happened to surfing if the Polynesians hadn't  taken to waves on their stomach.
