These new guys in the trade are amazed at how fast I can home in a screw either hand and not the one your're thinking of either.....
hey, i was going to mention something along the fast screw line.
problem with manual labor, which i do enjoy from time to time, my lady complaint that my hands became to rough, which isn't about my waza per say.
i tell ya that picking rocks to clear a field could produce tough fingers and other stuffs.
as far as dealing with finger grabs, i'd use the curve finger approach that rock climber use, might buy you a moment or two.
