Doperf, founded in Southern California, is committed to crafting high-end outdoor survival knives, premium pocket slip-joints, and top-tier kitchen blades. The name "Doperf" reflects our relentless pursuit of perfection in every knife we create.

Our founder, a passionate collector with hands-on experience across nearly every major brand worldwide, has tested blades in diverse real-world conditions. This deep expertise has fostered an obsession with knife aesthetics, proportions, and performance — driving us to design knives that seamlessly blend beauty, collectability, and functionality while rejecting bulky or unrefined designs.

At Doperf, we honor classic knife-making traditions while enhancing them with modern craftsmanship. Our advanced vacuum heat treatment ensures exceptional durability without relying solely on expensive powdered steels. By meticulously balancing hardness retention and toughness through precise tempering and cryogenic treatments, we refine every blade for peak performance.

With Doperf, you don’t just own a knife—you own a masterpiece of precision, craftsmanship, and innovation.
