One day, I looked for my old lego to increase my new collection of Kingdoms (after 10 years without acquiring castle). Those pieces are from the Black Knights, Wolfpack and the Dragon Masters. After cleaning them, I gathered the new weapons with the oldest ones and the first difference I noticed was the finish of the swords.
They used to be rigid and well defined compared to the new, although the finish is not well defined, now they are more flexible.
Is this a fault in quality or a mechanical solution to the swords and so they do not break so easily? (due to rigid objects are more likely to break than those which are flexible).
Update: Thank You both!
