The flashing is VERY sharp and even casually flipping the prop can slice your fingers to ribbons if you don't scrape it off.
Learned that the hard way. I was just spinning the prop by hand to prime my 46AX and the prop sliced into my finger like a razor. I have a scar on the underside of my middle finger now. I always sand down the edges of props now.
