THE
JANKA HARDNESS
The
Janka hardness test measures the force
required to embed a .44 inch steel
ball to half its diameter in wood.
It is one of the best measures of
the ability of a wood species to withstand
denting and wear. By the same token,
it is also a good indicator of how
hard or easy a species is to saw or
nail. Northern Red Oak, for example,
has a janka hardness rating of 1290.
Brazilian cherry, with a rating of
2350, is nearly twice as hard.if you
