Clear fake.
Note misspelling of word Arylate.
Some of the older genuine blades misspelled performance as "pefomance" but never to my knowledge as "peirformance", and the ones with a serial number that begins with N spell the word correctly (those are somewhat newer). I'm not sure about the M ones, though. Also, as someone already mentioned, placement of word polyarylate is incorrect.
Also, the plastic badge is not as flush to the wood as it would be for a real one and metal badge on back is not straight.
I have to say, though, that the first thing that seemed odd to me was the overall shape of the head.
