I got this broadhead from a friend.  Would appreciate it if anyone knows what kind it is.

Thanks,  Bob

Ben Pearson Switchblade.  c.1976

There's an insert that would have made them dual-blades/four edge.

   

Thanks Charles.  Is yours the real finish as you can see, mine looks like it was painted green?

They came in many colors.  I think that green is probably original.  I've seen them in green, yellow, white, gray and bronze.  Likely more.

Thanks again.   Besides the ferral, the shape looks very similiar to the old Bear razorheads.  Any idea on how they perform?

They fly and perform very well. The gren is one of the colors available, I have several like it. My favorite head though is still Zwickey.

The original version(yellow) was probably a bit stronger as the vent did not come as far down the ferrule. The brown head on bottom is the last version-notice the difference between the three heads in the bottom of the vent.
White=winter
green=spring
yellow=fall
brown= autumn
This is the head that Marv Clynke uses.
 

One more question; is the auxillary blade prone to breaking at the tip as it is not supported as compared to the Bear razorhead?  Cool looking broadhead though.  With the extra blade,  would seem to make a big entry and exit hole.

No problem with the bleeder blade breaking. The issue I had with late model like the brown one, I shot at a buck in Wis in the mid 70s and hit a tree.... imagine that!.... was the ferrule spread open. That's why I think the first version was stronger. Marv has no problems with the brown ones but I think he shoots them as a two blade.

Thanks for all the info.....maybe I'll give them a try this hunting season.

Many years ago I had some of the brown ones and the main blade snapped off the ferrule pretty easy. very weak braze/weld joint. They went in the trash pretty quick. Might have just been a bad batch but I could never trust them again to shoot at game.

Very informative....
