What do you mean? Many early swords and daggers as well as knives featured a wide ricasso for "ricasso grip" above the guard, i.e. putting the finger closer to the choil (commonly un-notched). There are samples of this dating back.... sheesh,
really far.
Didn't the "original" Bowie knife (1800s) feature something of a "finger choil"? (enlarged recessed ricasso above the guard)
And then there is Randall (1940s, not my pic)
And probably Gerber popularized it after that (1980s). So the idea of a choked-grip on the "blade" (i.e. ahead of the handle) may have originated in early European history or further back? And was popular by the 1800s, gaining popularity into the 1940s before the 1980s era of mass-production? How "new" are we talking?
Regarding puukko and other Nordic blades, how many are sharpened AFTER the blade is attached to the handle?
My understanding is that the choil was invented as a means of sharpening the entire edge (tip to heel) without scratching up the bolster or ricasso or ending up with a recurve or a dull section at the heel. Enlarging that choil to accommodate a finger is a natural progression for the "ricasso-grip" that some users may prefer to employ.
I agree that it can be done wrong, just as an un-notched choil can be done wrong. *shrug*
