Slipjoint Folding Knives FAQ
What is a slipjoint folding knife?
A slipjoint is a folding knife that does not lock open. It uses spring tension to hold the blade in place, but it can close if pressure is applied the wrong way.
How does a slipjoint stay open if it does not lock?
Slipjoints rely on a backspring that creates resistance at key points in the opening and closing arc. That tension helps the blade feel secure in normal cutting, but it is not a lock.
Are slipjoint knives safe for everyday carry?
They can be, as long as you use them for appropriate tasks and keep your fingers clear of the blade path when closing. They are best for everyday slicing and light utility work, not heavy prying or hard thrusting cuts.
Why choose a slipjoint instead of a locking knife?
Slipjoints are a classic, simple design that many people prefer for traditional carry and straightforward cutting tasks. If you want a deeper comparison of slipjoints vs. modern locking mechanisms, see our Folding Knife Lock Types guide.
