Thank you for all the nice comments.
hi Bruce. I have never tried anything but the tips with the 10-32 threads on them. If a saguaro needle hit one of those electronic boards, it may go through like a steel tip. They are tough and dead sharp.
Hi Dave. The rosewood ones have brass on both ends that adds to the weight. I did not use it with the corian because I could put good threads in that material but not so in the wood
