My all time fav-o-rite EDC folder is/was a converted Boker Full Auto Top Lock. (not speed lock)
Seem's, most time's I'm in a nine-line bind when I need some blade-assistance. Being left handed ain't the easiest in the assisted opening knife world. The release button on this top lock was just in the right place.
Used it multiple times a day for about 13 years before I lost it.
Prolly opened close to 3,000 Negra Modelo Beer bottles with it.
Fit my hand just rite!
My Boker Kalashnikov, is no-where near the Top Lock.
Just sayin'
