Sized appropriately, the Katana can jam up a finger crack, smear up a slab, or edge through an overhung sport climb. It styles a permanent moderate downturn--thanks to La Sportiva's P3 technology--and lower asymmetry for a balance between high performance and a comfier feel. Vibram's XS Edge rubber has a harder compound than Vibram's Grip, and it ensures long-lasting traction suitable for granite slabs, sandstone smears, and limestone edging.
