Hi Mike,
Sorry to hear that, I removed all the finger tips off my right hand a number of years back (not quite down to the bone though) with a handheld electric plane.
They have grown back remarkably well, even the fingerprints, although I have a large scar across each fingerprint now!
However, as the doctors said, I no longer have full feeling in my finger tips, but it's
LOT'S better than I ever imagined at the time, so it's probably not as bad as you currently fear.
If it's any help?, this is what happened with mine:
The hospital didn't even clean the finger tips, because they had stopped bleeding by the time I got there, they just used 'Flamazine' anti-burn cream and tubular bandages. Next they gave me a tetanus shot in my thigh, which left a little fountain of blood spurting on the floor, and left me limping for two weeks!.
I had to go to the hand clinic at the hospital, interspaced with my local doctors, both of whom just redressed the hand each time. After a fortnight or so it looked like they were getting no better, just bleeding any weeping every time they were redressed - then on the next hospital visit they had scabbed over, and the hospital didn't redress them, it was like having a tomato stuck on the end of each finger, and I went and bought my own bandages and surgical tape to cover them up.
It took about 16 or 17 days to that point, but even once the scabs had gone it took months for the fingers to stop feeling 'soft and fragile' - it's surprising how tough your fingers actually are.
So don't be too dispondent, it takes time, but they grow back amazingly - and I never missed a day off work either!
