Built for the Trade. Built to Last.

PrimeEx started with one problem: the tools on job sites weren't keeping up with the pros using them. Roofing knives dulled too fast. Blades snapped under real workloads. Replacements were overpriced and hard to find. We built PrimeEx to fix that.

Who We Are

We're a team that respects the trade. PrimeEx was founded by people who understand what it means to work in roofing, flooring, drywall, and construction — long days, demanding materials, and no room for tools that fail. Everything we make is designed with that reality in mind.

What We Build

Our core lineup is roofing knives and replacement blades — precision-ground, heavy-duty, and built for repeated use in tough conditions. We source high-grade materials and hold our manufacturing to standards that matter in the field, not just on a spec sheet. Every blade is designed to hold an edge longer so you're cutting more and stopping less.

Our Quality Standard

We don't cut corners on materials. Our blades are made from premium steel selected for hardness and edge retention. Our knife handles are engineered for grip and durability across temperature swings, wet conditions, and hard use. If it doesn't perform on the job, it doesn't carry the PrimeEx name.

Our Guarantee

We stand behind every tool we ship. If something isn't right, reach out — we'll make it right. No runaround, no fine print. That's the PrimeEx standard.

Built for roofers. Built for the pros who don't quit.
