I did wonder if the 24 indicated a 24 inch blade as the two 25's appear about an inch longer. Did your 65cm refer to the total length or only the blade?
A long shot, I know, but it seems worth the trouble to ask if your blade is 22 inches.

No that's a good hunch , however measuring it across the curve ( ie in a straight line ) it is 20.5 inches. Pity !
