Ipe - kills tools and edges, apparenty due to a very high silicate content, but makes great bows and is quite pretty in a chocolate brown way.
Purpleheart, as for Ipe, but more colourful, and fades from bright purple when exposed to sunlight.
Osage - hard and colourful. Fades/changes colour over time and has great chatoyance in soome pieces. Makes great bows (can you see a theme here...
). Might be the origin of the lyrics "Bring me my bow of burning gold".. bright yellow when cut, then fades through golden to deep brown or even purplish in some cases.
Hickory - not pretty as such, but tough as all heck
Yew - very pretty and lovely to work with - a nice crisp feel under an edged tool, but a bit soft for some applications
Amboina - hard and very very pretty - especially so with burl. Smells like black pepper when worked.
Maple - quilted and birdseye - beautiful but can be tricky to work, likes an abrading tool rather than edged I find.
Bamboo - not technically a wood, but SO versatile.
Eastern Red Cedar - not actually a cedar but a juniper - wonderful smell that lasts and beautiful rosy-pink coloured heartwood. Makes good bow bellies but too soft for handles etc
Padauk, cocobolo etc - all hard and pretty, but I only use them for accents and protective pieces.
