There were 10, 6 inch divers knives, made for employees who scuba dived. This was in the late 80's, I believe. I never saw one that long, but...Hey: custom made knives...
They also had jackets made by Tom Clinton and had the large Randall patches on the back. (The ones that Tom sold for years)
Hope this helps...& maybe Scott can clarify the date, etc.
