    I think it would actually be easier and faster to just crimp a new end on the cable…

    For those who don’t own a crimping tool, this is a saver. More important, this is totally in the spirit of “doing it yourself”.

    I remember about living in an apartment where Ethernet cable just came out of the wall. The plug was already broken. I was specifically disallowed to install a wall socket (go figure) so that broken ends could be simply fixed by anyone buying a new patch cable. Eventually, after a few months of frustration and acrobatic attempts to keep the plug from falling out, I had an opportunity to borrow the crimper and fix the plug – nobody in the vicinity had the tool or was willing to lend it for an evening.
