This is the last Cocobolo wood pen that I have....and ever will be able to turn. After a dozen or so beautiful pieces cut from a phenomenal block purchased from a terrific local tropical wood distributor, I became sensitized. I REALLY didn't want to believe it. Didn't want to accept it. Nothing is as detailed, nor figured, nor full of depth, detail and drama and color as a great piece of Cocobolo. I mean check out the photo attached. And.....I can't touch it anymore. Take care and turn well my brothers, but remember this. If you notice a rash....hives on your hands, arms or arm pits, or swelling around the eyes...or a cough that just won't go away...( sounds nasty eh? How about ALL of the above, all at once! ) be aware. The cause might be the very LAST thing you suspect. That beautiful tiny harmless piece of wood on your lathe. And once bitten by this beast, each time you expose yourself to the quinones released by the wood, your reaction will be more severe. Just lookin' out for my boys.
