I'm not sensitive to it either, and I've carved lots of parts from it with large tooth burrs and spindle/belt sanders. Just lucky I guess
I have fewer allergy/irritation problems from dust exposure now than when I worked in a cabinet shop. For me at least, occasional intense exposure to dust seems to cause fewer immediate problems than did 40 hour weeks of "background" exposure -- the shop had good dust collection, but I still got some all day, every working day.
Now the only irritation problems come from my day job!
