The Peña Custom Mula Front Flipper is a modern design so meticulously crafted it has the feel of a family heirloom. Like its namesake, the Mula (Mule) was designed to work long, hard hours in the field. With Enrique’s attention to fit and finish it is  also a pleasure to use. This edition features a snag-free front flipper design. In lieu of thumb studs, the tang of the blade has fine machined grooves for traction. The knife has a blasted 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,  titanium bolster lock, geared backspacer, 3D pocket clip with custom hardware and classic OD green micarta slabs. The Peña Custom Mula Front Flipper 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.
