I really need to find some sedimentry stone like Paipo's greywacke... although, I'm not sure if that's any easier on his burrs.
I'm afraid I'm just going to have to bite the bullet and buy some quality tools!

I think the stone you used for that wee character is a very tight/hard jasper! No wonder it ruined your cheap burrs.

I dont think greywacke is too bad; its those quartzy type stones that are some of the hardest on gear. Another sedimentary or silt-stone is argillite - technically a 'metamorphic' rock, as it has been baked hard by techtonic pressure/heat. This is what most Maori adzes were made from. Generally a dull grey/green, sometimes flecked, non-translucent. Its totally non-precious and would be free if you knew of a domestic occurance..?

For cheap-but-GOOD diamond gear, try a 'BUTW diamond' search on eBay. Ive bought off the guy a few times and can highly recommend the solid steel peripheral wheels! Ive never tried his burrs and am always dubious about those no-brand $10 packs of 20assrtd burrs - usually rubbish. Better to buy individually from a reputable manufacturer. Hongia burrs are the business if you can track them down. Worth every penny of the bit extra you will pay, and last for a long time.
