I owned both concurrently. The Delica was a current model and the Endura is an older model with an ATS-55 blade and a pointed tip. I ended up carrying the Delica because of its size. But I was not pleased with the blunter tip of the current model Delica. So I sold it and bought a Caly 3 to replace it. For my purposes the Caly 3 is a superior knife to the Delica in every way. It became my EDC knife. However, I did keep the Endura for those days when I need to carry a larger knife for self defense. The Delica and the Caly 3 are marginal in that role.
