Since the appearance of the liner lock, lockback knives have lost much of their popularity. Many manufacturers use that locking mechanism only on their economical models. But lockbacks do have advantages, that make them a good choice for certain applications and situations. For instance, lockback knives are robust and work well in dirty environments (mud, etc.). Hence my interest in high quality (not economical) lockbacks, and hence my question to all of you: "What are the best production lockback knives with one-hand opening and clip?"
