I do a lot of DIY/terminate the network cable. I used to only use the razor in my RJ-45 terminator. My friend suggested I get the lengths while I finish the wiring in my new house. So I bought this pair (his recommendation). After using it I am very frustrated with myself because I could have done my job much faster. If you want to make more than four or five cables, do yourself a favor and get some scissors. I'm sure you can find other things to work on as well.
