‘Puzzle Lock’ Folding Knife

[leadin]A custom knife with a new kind of locking mechanism on the blade is for sale and up for funding this month.[/leadin]

DRT Blades are handmade in the USA, in Thousand Oaks, Calif. Knifemaker Mark Bartschi has a new, one-of-a-kind folding knife called the Puzzle Lock.

It is unique because of a patent-pending locking design. A spring locks a “puzzle” shape piece of the blade into a corresponding slot.

It locks in place with a solid click, and the knife handle hinges on the blade, not the other way around.

The Puzzle Lock Folding Knife has a blade made of D-2 steel and its handle is 17-4 stainless steel. The scale is titanium.

Check it out on Kickstarter or DRT Blades. But be warned, this new kind of locking knife does not come cheap, starting at $615 for the handmade blade.

Beyond the folder, DRT Blades sells a few custom offerings. We love the look of the Helldog Tactical Knife (see above), and the Self Defense Credit Card Knife, $25, is pretty wild.

The credit card knife is made of titanium and just 0.032 inches thin. It is sold as a “micro knife that can fit into the smallest of places,” wallet card slots included.

DRT Blades’ whole line is available at drtblades.com.
