I stopped using Rocket heads for that reason - .027 Thickness just does not cut it IMO. The screw retaining system is prone to fail and the blades can also bend very easily. This along with their "dull" blades makes me wonder why they have such a loyal following.

Look into the Jackhammer line - .036 thick, sharper, tougher and better IMO.

They open quick - and I had a large entry and exit wound on my last deer.
