Gaston, just a quick fact: maple is not the hardest wood. It's in fact rather soft when you compare it to iron woods, hickory, and of course the actual hardest wood, Lignum Vitae -
https://en.wikipedia.org/wiki/Lignum_vitae
On the Janka Scale of Hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4500 lbf (compared with Olneya at 3260 lbf[4], African Blackwood at 2940 lbf, Hickory at 1820 lbf, red oak at 1290 lbf, Yellow Pine at 690 lbf, and Balsa at 100 lbf).
Hard maple, aka Rock maple is only a bit higher than red oak - at 1,450 lbf
