Features: The biggest issue beginners face when learning to comb pick is properly aligning the teeth of the comb directly under the pins. The Ergo Combs eliminate this problem completely using a vertical stop. Trading the versatility and flexibility of the Quad Combs for ease of use and speed of operation, the Ergo Combs are the fastest, easiest, and most comfortable comb picks available. While many locks that can be combed have different pin spacing and depths, the Ergo Combs were specifically designed to open the most common locks that are vulnerable to comb picking, maximizing capability, speed, and efficiency. Each comb features the make and model of compatible locks on the handle for easy reference. How to Use: Insert the comb until it stops with the teeth facing the pins. Lift vertically toward the pins.
