This additional penetration could have been used to push greater cutting surface. Obviously, they first have to be accurate so you can hit the vitals or what is the point.
The action of the blades swinging open will take up energy to accomplish. How much is debated, but IMHO it is there.
I was curious, so I tried to find the cutting surface of your beloved Thunderhead razors, but could not. I only found this test completed by outdoor life about 1 year ago:

When you get a spare minute, measure the cutting surface length on one of the blades of your Thunderheads (Hypotenuse of the blade). I am curious to see how the total cutting surface of the Thunderhead compares.
Dead Ringer makes a smaller head called the Rampage, but thought I would give these a try. As you have said previously, the Thunderheads work for you. I am curious to see how these will work and whether or not I will get the exit holes consistently.
