Our Story

Owen & Jason are known in the rugby world for hard work, striving for excellence and always pushing the boundaries of what peak performance means in professional rugby.

They needed more out of their traditional training machinery and decided to deploy the classic kiwi mentality ‘if there’s a problem, fix it yourself.' The Ironback Rig was devised to fill the gaps with traditional scrum training machines. 

Ironback Scrum development continued and the Sharpener was born! Designed to apply that same technology to the outdoors, it continues to provide advanced training options.

Since then they have identified that there is not only a requirement for equipment that meets the needs of players who need to learn the intricacies of scrummaging, there is also a unique opportunity to provide fitness and conditioning equipment focussed on meeting the everyday strength and conditioning needs of every rugby player.


Owen Franks' impressive career spans a twelve-year period with multiple teams. Franks made his debut in 2009 for the Crusaders and over the next decade played 150 games ranking him the fifth-most capped Crusader.

He is one of only 21 players to win the Rugby World Cup multiple times. He served an integral role at tight-head prop, starting in all of the knockout rounds for both World Cups.

Franks ventured overseas to play for the Northampton Saints in 2019 and helped the Saints claim their first win on French soil since 2011 reaching the knock-out stages of the Heineken Champions Cup. 

He has since returned to New Zealand, and currently plays for the Hurricanes.
