The B and T ratings on BD picks differentiate the intended use and strength of the ice tool. T-rated tools are designed for steep ice climbing, while B-rated tools are intended for mountaineering and general ice climbing. The ratings are determined by rigorous testing, which includes a 3-point bend test on the shaft, strength tests on the head/shaft interface, and a torque test on the pick. T-rated components have higher requirements and are generally more durable and stronger than B-rated components.
Choosing the right tool and pick depends on personal preference and the type of climbing. For mountaineering, the Raven, Raven with Grip, and Raven Pro are recommended, while the Raven Ultra is suitable for ski mountaineering. For technical climbing, BD's tech tools such as the Cobra or Viper with leashes, or the Fusion or Reactor for leashless climbing, are the obvious choices. T-picks are tougher and more durable, while B picks like the Laser are intended for steep ice and may be less durable. Competence and technique can also affect the durability of the picks.
