I love Cocobolo, too. I always have. I remember how happy I was the first time I was able to upgrade a pistol to cocobolo grips. In it's finished state, neither Cocobolo nor African Blackwood give me any problems. But the dust is no bueno for me. And people need to heed Steve and JMForge's advice... you DO build up an allergy to it over time. I made a bunch of Cocobolo knives before I had problems. I always wore a respirator, but over time I got to where if I could still smell the dust on me- or on my bench even days later, it was like getting a quick whiff of pepper spray. I need to give away the last of my blocks of it, too. Just handling them, if they are rough and dusty, then forgetting and touching my face or eyes later is enough for it to start burning.
I'll look in my stash and see what I still have of it, because at one time I had some absolutely gorgeous blocks of it. Free to a good home. I'll post pics when I find it.
