mrpenguin, I'm guessing you are relatively new to the sport, as the Bear Razorhead needs no Billy Mays or Jimmy Football sales pitch to prove its metal.
How about, elephant, rhino, cape buffalo, lion, tiger, and myriad other ultra large game taken efficiently over a 53 year period? That should tell you.
Now, if you need new input, I will tell you they have worked very well for me for over 45 years.
They are very easy to sharpen in the field, durable, and have built-in mojo...whatever that is 8^).
Now about the brand new ones, that don't even look like real Bear Razorheads, and aren't made by Bear Archery? No comment.
And, the old green/tan ones are readily available if you keep an eye out. Bear could make millions of them every year; the Bear Razorhead machine spit one out every five seconds.
