Hi Bob,
I too use a simple method that does not involve a comb. After cutting off a small clump from the hide, I grasp the tips with thumb and finger, then grab the cut end with the other thumb and finger and after a bit of rolling the hair lightly back and forth pull out most of the underfur with the off hand. Works great. I also brush the hair back and forth a bit with a bodkin to get most of what is left.
Regards,
Gandolf
