The oak shafts will be perfect for the custom work I am planning. Out of the 10 that I purchased one had a flaw that was not visible until it broke. I made contact with the Atlatl Madness and they stated they would replace the defective shaft. What more can you ask for? Anytime you work with organic materials like wood, it is possible to have defects and if they are while to replace it, THEY HAVE MY BUSINESS!
