Keep your design simple, keep your materials simple. A knife made by a master by simple materials will far surpass a knife made by a new guy with the most expensive materials one can get. Look into AEB-L/14c28n stainless steels, IF you can get someone to heat treat them ofcourse, same goes for your carbon steels (80Crv2 f.e), but if you do your own heattreat they will be harder to mess up, however i still recommend for you to seek profesional HT. Next thing i would mention is, SAFTEY, instead of spending money on the high end materials, get some saftey equipment, like a respirator etc. One breath from an exotic wood can make you sit down and get humbled.
