A comment on recent answer suggests that kernmantle ropes are more easily damaged than a conventional twisted rope. This is contrary to what I learned very long ago. So far I've been unable to find a general reference on how different ropes need to be handled, and what tools can be used with each.
Please do NOT answer with generalities like 'keep it clean, don't step on it, check after each use' I'm looking for usage differences.
Example: One rope company said that double braid rope shouldn't be used where you have a running bend over a short radius, such as a pulley or carabiner, as the inner rope is 'milked' with the slack running to one end, and most of the load then falling on the inner rope. (I've had this slip happen with shoe laces...)
