"I am operating from rather vague memory banks but I think that Jim Dougherty may have been involved in the design of a commercial model patterned after Howards modification. It was called a "Little Shaver" and had cutouts to hold the razor blades. I don't believe it sold well."
Yes, Jim was involved in marketing the "Little Shaver" broadhead. It was a two blade that was slotted to take Schick injector razor blades, later they came out with a 3 blade version. I used both for a few years, I'm sure there's some of the old heads laying on the bench in the back of my shop.
$5.00 a dozen, you know that was a looong time ago.
