It doesn't really recall that story. It recalls a story in which a very 
worn axe head and splintery handle were replaced in one foul (rather 
than fell) swoop by a gleaming new axe head and handle using the 
original specs. Terrific for anyone wanting a sturdy new axe, not so 
much fun for the original axe. Luckily axes haven't got a clue.
