Great to hear al these successes with hand drill.
Just a comment on tough hands - I have been not doing practice for a year or two. Then got back to it for the Bushmoot. I must have made 10 to 15 coals. Throughout my hands have remained soft with no calluses or blisters.
I think there may be three reasons for this. I mostly used hand drills with a thicker end at the top - much more comfortable! Another thing is that someone in a workshop noticed that I use not so much the whole palm of the hand, but the smooth muscular part of the palm on the pinky/ little finger side of the palm. Also, keeping hands moist reduces damage.

If at first you don't succeed - pause, reflect, change something and try again.
