Hardness
The most important aspect of the shaft is the type of wood it's made with.
Ziricote is an extremely strong wood from Belize; in fact, it's one of the strongest out there.
Ziricote has a Janka hardness of 1970 lbf, which to most people doesn't mean much.
The Janka scale measures the wood's resistance to indentation and overall "hardness".
This isn’t a measure of durability in terms of snapped shafts, it’s a resistance to dents, but there is correlation.
In comparison, here are other woods you may have heard of:
Janka Hardness (lbs) --- Dent Resistance
While Ziricote is Tomahawk Lacrosse's least "hard" wood, its competing with a tough crowd.
Ziricote is still harder than any other wood used for lacrosse sticks on the market and is definitely harder than metal shafts on the market, which is important in the game when you want to lay a hard check into your opponents and walk away with a dent-free shaft.
