Assuming (correctly?) that mammoth ivory can be purchased legally online, anyone know of an updated online supplier (shipping overseas)? I need a few bits for decorating some inlays. Maybe someone who purchased more than he needs i swilling to ship some bits? And to conclude: do I treat it with the regular tools or will I dull the tools quickly? Thanks and have a good one, Max
Looking around the knifemakers might turn some up - you could try

You need to work it with traditional ivory working tools. If you can find a copy, try something Victorian like a reprint of Holzappfell's "Ornamental Turning".
It won't dull the tools especially fast, but it's hard going with hand tools and doesn't handle at all like wood. Wood is fibrous and most are our cutting tools make use of this. It's also elastic, so a knife-like separatng cut will get you through things, but ivory needs that whole kerf to be scraped out (so rip teeeth not crosscuts).
Ivory handles like a hard, brittle plastic and generally needs more of a scraping action. For hand-carving, try using metal engraver's gravers, not chisels and gouges. To saw it, I suggest a fine-tooth narrow-kerf saw like a gent's saw, or even a hacksaw (huge kerf though), rather than a tenon saw. Hard waxes are good for finishing.
To identify real mammoth, look at the Schreger patterns

just love that graph)
BTW - you might want a _good_ respirator too. Working ivory stinks !
ivory is harder than wood, but the grain is so tight and the absence of grit make it a joy to work. it doesn't dull the tools particularly, but the tools do need to be very sharp.
I've done some work with tagua nut vegetable ivory and it was a most irritating material. The nuts split with a central crack as they dry. It's great if you want a small piece, or even a ring, but there's no way to get a solid piece out of one.
