Prevents cutting: The sleeve acts as a protective barrier between the fishing line and the sharp edge of the hook, preventing the line from being cut by the hook itself or by the teeth of a fish when hooked. Cushioning effect: When crimped onto the line, the sleeve creates a small cushion between the lure and the hook set, which can help prevent line breakage, especially when dealing with strong fish or deep drops. Ideal for deep drop rigs: Due to the added protection and cushioning, crimp sleeves are particularly beneficial for deep drop fishing where the line is under significant tension.
