Company Background

The slide-hammer concept has been around for a long time. In fact the inspiration for the Slammer tool was an old mining Jack pick that company founder T.J Irvin (aka Slammerman), had seen in his Grandad’s shed. But the design and materials used for the Slammer has been a 23-year evolution of numerous prototypes to make the tool as sturdy and robust as possible. T.J wanted a simple, indestructible multi-purpose tool for his own tough, labour-intensive jobs. When clients, friends and co-workers saw the Slammer and wanted one, the Slammer Ltd was born. It is T.J’s passion and belief in the Slammer tool that has been the driving force to create this business along with the encouragement of other Slammer users who appreciate it’s efficacy.


Our vision is to provide high quality, efficient and affordable tools that make hard, manual jobs easier. We want people to live happier, healthier and more productive lives and work in a way that is better for them, the environment and the economy. 

We aim to:

  • create simple, strong connections around the world using our utility design patents by establishing mutually beneficial working relationships with licensed contractors and distributors.
  • maintain a socially and environmentally conscious business.
  • educate people as to how and why they should use our products.
  • educate our customers on how to get the best from their tools and how to maintain them for optimal performance.

We have filed our PCT patent around the world to engage contract manufacturers in targeted countries to supply the world's biggest markets with our tools.


Our philosophy is to empower the labour force and encourage people to be more self-reliant. Using Slammer tools can reduce the use of heavy machinery and herbicides which in turn is better for the environment. The Slammer tool provides an easy to use alternative to machinery in undeveloped and emerging economies, creating jobs and economic growth. All Slammers come packaged in reused mountain-bike tyres. These act as a sheath for the tool and keeps un-recyclable tyres out of the landfill.
