The Bear Razorhead Machine (yes machine..Fred's invention) spit out a broadhead every five seconds. So you may want to add to that 3 million number made.
Conservatively speaking, that means Bear turned out 1,440,000 Razorheads each year...based on a forty hour week only..one shift. So in three years time, they would have made over 4 million heads. If you ever get the chance, watch the Bear Video "Rural Route 1, Grayling, Michigan."
It shows the machine in motion...very amazing. Fred was quite a designer/inventor as well as a bowyer.
