A history on the mat
Dave's training
journey
A few archival moments from the traditional martial arts and weapons-training background behind the program coming to Blur MA.
A focused adult offering
Be ready
without living
in fear.
This is not a sport-martial-arts class. It is an adult-focused self-defense program for people who want to understand pressure, move with more confidence, and build practical personal-safety habits.
A traditional karate black belt for 25 years, Dave later expanded into stick and knife fighting and found the SPEAR System to be the bridge into the broader weapons training he values. His background also includes prior service as a police SWAT officer and police academy instructor. He loves teaching this material and will always include stick and knife fighting in his classes, with an approach built to be accessible for adults with or without previous training experience.
