Hi Marc,
Thanks for the references!
To clarify my side, the Guanches ( 
Wikipedia link) had a long sword/club they called a magado or magido (it's listed as a mace on Wikipedia, but other references say it was long, wooden and sword-like).  That's what I was wondering about.  Supposedly, the magido was a chief's weapon, and they actually beat the Spaniards with this and other indigenous weapons, which makes for a good story (and might be true.  A 15th Century British sailor with a quarterstaff took on a number of Spanish swordsman in duels, and beat them all).  
 I can easily believe that the guanches got the idea and the name "magido" from Basque whalers, but I was wondering what the Canary Island version looked like.  And yes, I've read everything I can get my hands on regarding Juego del palo.  I'm unclear on how much that sport is a descendent of the guanche martial traditions, and how much came over with the Europeans.
Best,
F
