We are fortunate to have some good two, three, and four blades blades to pick from, but what did Saxton Pope, Art Young, Compton and Ishi use? How about some that followed them like Fred Bear, Pearson, Howard Hill, Glenn St. Charles and many others? Some used stone points, others made crude two blades tied into their wood shafts. Fred Bear came out with the Razorhead in the 50's after Cliff Zwickey added a bleeder to his two blade. The differences might have been they got what they used razor sharp and/or serrated. They didn't use 175 gr three blades. The reason for bringing this up, is a lot of bowhunters do not know how to sharpen any broadhead. I have a box of crap, heads that someone tried to sharpen on a grinding wheel. I recall stories about recovering game through their tracking skills. In some cases nothing can make up for a bad shot, or gut shot animal.
