I’ve been looking into the 15223 myself, and while it might seem like just a minor evolution at first glance, those subtle enhancements really add up if you appreciate a modern twist on a classic design. For collectors who value understated refinement over flashy gimmicks, it offers real merit. It’s not a miracle tool, but it does deliver improved reliability and comfort compared to its predecessors, making it a worthwhile pick for those in the know.
