While I was in Exmouth, I made these knives. Bought the blades on-line and fitted the handles from four different timbers – Jarrah, Driftwood (possibly Mangrove), Australian Oak and Karri. Mind you, I can’t be sure about the species – best guess only!
The two straight edged knives work well for various woodwork tasks. The other two are risky if used to cut or carve – the curved edge means they slip away as easy as. I believe the spade shaped blade could be useful for cutting leather, veneer, etc on a backing board.
