The Razorhead VWS Double Bevel is constructed from high-grade stainless steel, engineered for better arrow flight and maximum cutting surface to provide optimum penetration. In conjunction with the 150gr heads or field points, you can add one of the three included inserts: magnesium insert will make a 175gr head, aluminum insert will make a 200gr head, and a stainless-steel insert will make a 250gr head.
The variable weighted inserts work great and allow me to test different arrow setups. I only give it a 4 star rating because two of the three Aluminum inserts were not in tolerance and were too large and did not initially fit my arrow inserts. I had to file them down in order to make them usable. All the other weighted inserts fit fine right out of the package. I haven't hunted with the broadheads yet, but they appear well made and are extremely sharp, as they should be.
