On collaborating with Marcaida

Kuya Doug and I were introduced to one another in 2013. We were brought together by a project that—fortunate for both of us—never came to fruition. First we spent time getting to know one another’s style as martial art practitioners. Then, we discussed what we liked and disliked in knives.

Doug Marcaida is a master practitioner, and I am an edge-and-impact weapons visionary, of sorts. A new vision of knives formed between us.

When not thinking outside the box, I enjoy developing within an envelope that seems to have exacerbated all the possible solutions.

I enjoy challenging questions. Anything from “wouldn’t it be cool if” to “can a Karambit share some to the advantages of a straight blade and still be a Karambit?” These are the conversations that knife-guys have.. Not exactly an episode of Forged in Fire, but many such conversations bear the most delightful fruit.
