We’re in the age of locking knives. Each major knife brand has at least one of its own proprietary locking mechanisms. There’s the Tri-Ad Lock, the Compression Lock, the AXIS Lock, the Arc Lock, the Reeve Integral Lock, and many more.
But it wasn’t always like that.
Not long ago, most knives were slipjoint knives. These folding knives use backsprings to keep a blade open or closed, even though it’s not technically locked. And before that, there were friction folders.
In fact, the first folding knives ever made were friction folders. Let’s find out what these actually are.
What is a Friction Folder?
A friction folder is a folding knife that doesn’t use a lock or springs. It uses the handle’s friction against the tang to stay open. Over the years, the design has adapted to feature an extended tang. This allows the user’s hand to keep the blade from folding shut.
As you can tell by the description, friction folders aren’t for hard use. They are excellent for light cutting, but put any pressure on the spine and your fingers will be toast.
