All About Pocket Knives

I am curious, when did Queen discontinue the patented interframe Barlow design (as seen on the #22 Barlow and #49 Big Chief) in favor of a more traditional design? I know when Queen was in business, they were showing the interframe design in catalogs in the 1990s; but the ones being sold at that time (a couple years before they went out of business) were of the more traditional design that had three pins and separate bolsters and liners.

Cody, Can't say when they were discontinued. I have this #22 pattern dated 1992. The #45 Big Chief has no date, just patent # 2728139 and looks much older. Good luck. J.O'.

Fellers the patent number for the knives in question is #2728139. A man by the name of Eric Erickson applied for the patent using the style of frame construction that is used with the #45 Big Chief and several of the small Queen Barlow models had the same construction, the ones with the closed up aluminium frame.

The #22 last showed up in the Queen Catalogs in the 2002-2003 Annual Catalog. The Big Chief Series was continued in production until 2008, at least they were still in the Catalog.
