I would go with the Grip over the Endura 4 because I like the beefier handles rather than the skinny Endura handle and on a knife that size the axis lock seems perfect. I like lockbacks when the knife gets really big, but the Grip and Endura are middle sized folders I would say. But if yor talking about the Mini-Grip or the Delica I prefer the Delica just because in my hand the Mini-grip handle doesnt fit me well when its that small but the Delica has a little more handle.
