Welcome to the Tharwa Valley Forge

We aim to be the best knifemaking school in Australia, offering a wide range of courses and opportunities to learn and share skills. Regular classes are scheduled in a variety of topics. Since we started running classes, hundreds of people have been introduced to the art of custom knife making and successfully made their first knives.

The Tharwa Valley Forge was established in 2003 by bladesmith Karim Haddad to create high quality knives and tools, and to teach the skills necessary to do this. Karim was trained by Australia's first Master Bladesmith, Thomas Gerner, in the early 1990's in Western Australia. The Forge is located in village of Tharwa,  just south of Canberra, Australia.

Our website encourages this continual learning through sharing resources, tutorials and articles. We are always interested in feedback on how to make this site better. We hope you learn something from your visit, and come back soon and see us again.


This is a tutorial on how to build a simple LPG venturi burner. The parts cost around $60 AUD without the regulator (which can be another $100). The forge's atmosphere can be adjusted by twisting the upright pipe, which varies the amout of air sucked in.

Please be careful when working with gas. If you don't know what you are doing, find someone who does.
