Tuneability, bombproof construction, and simple resharpening define the MD3.
It's short and stubby profile makes it an excellent flier and relatively easy to tune. It puts far less leverage on your arrow component. Allowing you to spin straighter, longer.
The MD3's pyramid shape makes it virtually immune to bending or breaking.
Easily touch up your edge on a flat stone or strop without a jig.
An extremely low profile ferrule allows this head to penetrate any medium with significantly less force than comparable 3:1 two blade.
We chose a treated S7 tool steel for the MD3 for one reason; edge retention.
At 59 RHC, it will take some effort to sharpen... but it will take some effort to dull, too. Staying sharp all the way through an animal is KEY.
