Old blade, new edge.
The way to bring this tool back to life is with pressure, friction and controlled damage.
The old dull metal must be removed at the right angle to reveal a new cutting edge.
Some material is lost in the exchange, there is slightly less machete left when the process os finished.
As soon as use it the first time you understand why the sacrifice was necessary.
The task at hand requires the right tools, in the right condition.
I am my greatest tool, and same rules apply to the condition of the self. As above, so below.
This is the way.
