I got a bit on the clip hangers. They were a highly advertised item when 1st sold because the clip could be switched side to side was a new thing.
Let me see what I can dig up..
Starting in 11/94 a patent was applied for for the clip hanger knife system The detachable clip and a sheath were part of the patent.
Seems our own Phil Gibbs of Camillus and Dave Swinden and others at Schrade were filing a lot of patents during the late 80's and into the 90's.
There were monthly meetings discussing the design of the knife and its display until in 3/95 4 orders were entered. I'll dig up the production numbers too.
The CH7S 96,000 the CH3S 48,000 CH7SCHP (clam pack) 24,000 and the CH3SCHP 12,000. along with an order for the unique counter display was quite and order.
Later tonight I'll create a section on the web site complete with the detail plans for both knives. The CH7 was retailed at 39.95 and the CH3 at 29.95
