The clip point design provides superior piercing capability compared to drop point alternatives, while the stonewashed finish reduces glare and conceals wear patterns. The glass-reinforced nylon handle with orange backspacer offers enhanced grip texture and impact resistance that outperforms standard polymer constructions.
