I see it recommended often for people to condition there strops with some neatsfoot oil , now I love neatsfoot oil got a 20ltr drum of it in the shed have used it on leather hunting gear and hides Ive tanned over the years in my opion its the one of the best leather conditioners there is ..but it must be remembered a little goes a loooooooong way , as to much will create moisture and eventualy ROT leather ...so remember a little goes along way
