Can sharp spots on a Brake Bar Rack or Figure 8 descender be smoothed out?

The correct answer is that sharp spots on a Brake Bar Rack or Figure 8 descender can be smoothed out using emery paper. This approach is effective because emery paper, which is abrasive, can help remove small imperfections and sharp edges that develop over time due to wear and tear. By gently rubbing the emery paper against the rough spots, you can restore a smoother surface to the equipment, which is crucial for safe rope handling and to prevent damage to the rope itself.

It's essential to regularly inspect climbing and rescue gear for any signs of wear, such as sharp edges, as they can pose safety risks during use. While some options like replacing equipment or using specific tools may also address damage, emery paper offers a convenient and effective method for minor issues without the immediate need for replacement. The use of water, on the other hand, does not serve any purpose in addressing sharp edges and could potentially lead to corrosion if moisture is trapped in the equipment.
