The PocketMaster is a compact solid wood training block designed for finger strength and grip development through loaded hangs and dead hang training. At 90 × 100 × 30 mm and 190 g, it fits in a gym bag and can be used anywhere — at home, at the gym, or at the crag. It offers four edge depths (6, 10, 14, and 18 mm) and two pinch surfaces (30 mm and 100 mm), covering the range of grip positions relevant to both climbing training and finger rehabilitation. For climbers returning from injury, the variety of edge depths allows precise load management during progressive tendon loading protocols.
