Cutting diameter alone does not tell you anything. Cutting diameter plus the number of blades tells the whole story concerning total ammount of tissue being cut as the broadhead passes thru the animal.
Take theoriginal slick trickmagnumand Muzzy MX4 at 1.125" cutting diameter. It's four blades add up to a total cutof 2.25 inches.
The GrizTrick is a 1.25" four blade for a total cut of 2.5 inches. That's friggin huge.
To compare a Rage 3 blade has a cutting diameter of 1.5 inches for a total cut of 2.25 inches. Equal to the Slick trick and less than the new Grizz trick.
Even with expandables there are only a few that have a total cut more than 2 - 2.5 inches.
Even the super wide Hypershock 125 only has 2.75 inches of total cutting ability. This is one of the widest broadheads on the market.
You're exactly right. That's why I'm waiting for Slick Trick to make a 1.5" four blade! That would give you a full 3" of total cut. I'm sure 85 ft lbs of KE would handle that just fine.
With my FOBS, I've shot Spitfires with the BLADES OPEN and it hit the same mark as my field points! I know these things can handle a 1.5" fixed blade. Somebody just MAKE one and I promise I'll buy it.
