Hi,
Yes, I noticed the same in examples of the 'crusaders' pair blister pack I acquired recently: they have the 'new' sword, but the package artwork still shows the old one with the downward-curving quillons.
I get the same impression as others: Playmobil is now using this version as the standard, and I suspect the older version will be phased out. It does make the sword far easier for a Klicky with cuffs or armour to hold.
I wonder, though: what made them decide to change? Complaints from customers, or someone in the design team finally noticing?
Cheers,
AndrewL
