Jack has spent the last decade training, operating and instructing on the frontlines of emergency services/first responders in Australia. He believes that while there is no substitute for strong foundational and ongoing training, you absolutely need the right tools and equipment to achieve mission success.


Jack is also an everyday carry (EDC) enthusiast, inspired by the skill and mastery of the makers, crafters and artisans around the world. These products could be technical apparel, personal defensive equipment, knives, wallets, pens, torches, carry gear etc – each has a purpose but is designed to reflect our professional needs as well as personal creative expression.


Regardless of what you do for profession or passion, selection of what you choose to carry is weighted against many variables – practicality vs versatility, individual expression vs belonging, and necessity vs because-I-can.

GRSN aims to forge and supply you with rugged yet premium everyday carry accessories and more so that you can focus on chasing your ambitions and securing mission success.

To achieve this, Jack set out to look for an industrial designer with 3D printing expertise to create the first prototypes - he discovered Yan and very quickly a shared vision to establish the GRSN brand was formed.
