In this guide you can explore the company and learn everything you need to know about the patented tech that makes Vulcan Grinders so special.

The skinny on Vulcan Grinders 

Vulcan Grinders was founded to make weed grinders a lot more inclusive for people who need them. Classic manual grinders can be hard for people with conditions like Parkinson’s, arthritis, or carpal tunnel syndrome to use, so the founder of the company set out to make something that worked effortlessly. The final result was a fully magnetic grinder made from rare earth magnets and aerospace-grade aluminum that delivers a superior grind and components that are built to last.

Subsequently, a design engineer joined the team, and together, they built the first prototype. It took meticulous planning and multiple iterations, spanning over 18 months and four molds, to achieve the final and groundbreaking Vulcan Grinder you see today.
