Any knappers on here? I'm trying to find the best commercially

I bought some porcelain tile and it's been alright, but you can see from the flake scars the material scales and breaks a little too easily.

Why not just get flint?

Could always try glass and I've also seen Agate as well knapped, dunno how they do it exactly but the principle should be similar

Many are made from talc, that won't work. You just need to find the right kind, actual porcelain.

Glass is good, but has a totally different look.

You can order chert cobbles. I have no experience doing this, but I imagine the weight makes delivery expensive.

Too bad you don't have local materials. I have chalky ground here, so plenty of flint.

I tiles knap like ass. Start drinking Jager and do indirect percussion on the bottoms.

I usually only practice when I'm camping, typically on discarded beer bottles. Glass seems to be the best material as far as uniformity and flake size goes. Plus, garbage is free.

too much trace lead...

Try bottle glass, old porcelain (hit up an estate sale), stuff like that. The main thing is you want it to be homogenous so the force propagates evenly through the material. Look up Kimberley points - the Australian Aborigines make them out of all sorts of modern materials, e.g. old telephone wire insulators.
