Yes the swords they have are fantastic, the messers are especially my favorite. I have also seen all the weapons they hold in storage and they are amazing. They have a couple of schiavonnas, lots of yagatans and even another zweihander who's blade is forge welded from two pieces and and looks really bizarre. I wish one day they can properly display them all.
I guess so they had to be very strong since they faced constant threats from the turks and their own nobility.
