Chris, I have made kydex sheaths, or use to, I have just recieved the latest brochure from a Melbourne company that I got all of my gear from, send your address again buddy and it will be in the post next day.
It is great to work with!
Also, buy your kydex from 'Caddalac Plastics in Melbourne, cheapest around, about $50 for a 6x4 sheet.
Hows that Coot going buddy!
