says the “sunfish” pattern “seems to be a mid to late 19th century American pattern”. Says despite their being sometimes called an “old English rope knife”, “I have seen no evidence that the sunfish is either English or a rope knife”.
also says electrician’s knives having a combination of spear master blade with a locking screwdriver are based on the U.S. military specification Tl-29 introduced around 1917.
He also says of the Congress pattern “Not only is the Congress a purely American pattern, for most of its history it was a purely southern pattern.........English firms and the big northeastern cutlery manufacturers such as Remington and New York Knife Company made Congress patterns in large numbers but they mainly distributed them through wholesalers in the southeast.”
I believe the scout/utility pattern would possibly qualify as being of American origin. Again referencing Levine’s
, it says this pattern “seems to have been a cross between the American equal-end cattle knife and German and Swiss multi-bladed hunter’s and soldier’s knives.........an inexpensive home-grown substitute for the costly horseman’s and sportsman’s knives long imported from Europe.”
We know from more recent times Case has introduced new patterns like the SlimLock and Russlock.
All of these are variations on old patterns like the “jack” knife so I supposed it’s a matter of semantics as to whether you consider them as being “new”.
