i think muzzy heads have gotten alot less durable over the years. i still like seeing this one my dad has in his box from years ago that he shot through a deer and hit a rock and all it did was bend one blade and squish the tip alittle used to be crazzy tough heads but i also think it was a really heavy head. ive seen alot of people pointing to the ferlues bending anymore and the blades are not bad but def not as tought as something resharponable but thats the trade off of being able to replace to blades i guess.
