The guy on ebay said, about the measurements:
Still doesn't seem quite right... oh well, I won't be bidding on it anyway...
I have measured it again and sorry the blade is 4mm. The total measurement from the tip of the blade to the end of the handle is aprox 220mm the blade is 103 mm and handle 115 mm. I know this only comes to 218 bot i did say 220 aprox. The maker is Alan wood and he makes theses in batches and there are sometimes slight different measurements in different batches as the are all different cause of being hand made.
