My favorite bearing block for bow and drill friction fire is made from Teflon. I had some left over from a telescope build and made these two up. The larger one is just held as is in the hand with the middle finger through the lanyard.
This one is a knife fob that is held as shown. The advantage of using Teflon is the nearly zero friction and the light weight.
