Can an Axe Break a Diamond? Understanding Diamond Hardness

Diamonds are the hardest material on the Mohs' scale of mineral hardness, which means they can only be scratched or cut by another diamond. Axes, on the other hand, are typically made of steel, which has a Mohs hardness of 5.5. Thus, an axe cannot cut or break a diamond and would instead be damaged if you tried to use it to break a diamond.
