The Peña Mula is a modern design so meticulously crafted it has the feel of a handed down family heirloom. Like its namesake, Mula (Mule) it was designed to work hard but also be a pleasure to use. The knife has an antiqued tumbled bolster, clean lines and a classic drop point blade profile flawlessly finished in hand rubbed satin. The modern elements of a ceramic bearing flipper nest the blade perfectly in the bolster lock handle when closed. Deployment is effortless from the dual thumb studs, followed by a smooth strong lock up. Premium materials include a CPM154 blade, antiqued bronze titanium bolster lock, geared backspacer, 3D pocket clip and custom hardware and classic OD green micarta slabs. The Peña Mula is an honest hardworking knife finished with exceptional detail, promising to be handed down to the next generation.

Behind the Scenes with Peña Knives

Enrique Peña has had a lifelong fascination with knives that led him to open his own shop in 2005 in Laredo, Texas. Known for traditional patterns of exceptional fit and finish, he has honed his craft making the classics. He credits his friend Armando Flores for helping him with his first knife. Later it was Bill Ruple and Rusty Preston that helped to refine his skills. Enrique is not only an exceptional knifemaker but a talented leather worker as well. He has recently been branching out into modern designs that retain classic elements and the superlative fit and finish he is known for.
