A typical set of stairs has ~12 steps to the basement, maybe more - in
other words you have at least 50 board feet of oak. Go price that
against the price of a blade.


Against a couple of blade sharpenings, perhaps more, given that there has
been 70 years of dirt ground into the porous oak by passing feet.

Then there are the 70 cycles that a wood already infamous for its brittle
and splintery nature has used to become more so.
