A lockback knife represents one of the most trusted and time-tested locking mechanisms in the knife industry. Whether you’re an EDC enthusiast or just starting to explore the world of folding knives, understanding lockback knives is essential for making informed decisions about your cutting tools. This comprehensive guide will walk you through everything you need to know about this classic knife lock design.
What Is a Lockback Knife and How Does It Work?
A lockback knife, also known as a backlock, features a distinctive locking mechanism located on the back of the handle. The mechanism works through a spring-loaded bar that engages with a notch in the back of the blade’s tang when the knife is opened. When you close the knife, pushing down on the exposed part of the lock releases the blade.

Originally popularized by pocket knife manufacturers in the early 20th century, this design has stood the test of time due to its reliability and straightforward operation.
