All About Pocket Knives

Hello:
Ran across a couple of pretty nice knives. Need some info on maker. Has his knives appreciated, caught up with retail or deminished in price since 80's. I find a few, but they are newer.
His and spouses name are Devon "Butch" Beaver and Judy. Made knives in Phoenix 1979 to late 90's or eary 21st century. No trails to current location. Living or deceased. Any info would be nice.

Hello Mossdancer, Found some info in Knifes 93 by Ken Warner, pages 153,175,204. Saw some of his knives many years ago. Very high quality. Have not heard if he is still making knives or still living. Robert
