Klein Tools Ratcheting Modular Cable Crimper | $35 | Amazon
Ah, the cable crimper. It’s one of those tools you’re only dimly aware exists, and you never need, except that you do need it and the only reason you don’t have one is because you always just figure out another way to do the thing when that need arises. Problem is, you end up doing a crappier job than you could if you just had something like this Klein Tools cable crimper, which is handily on sale for $10 off at Amazon right now. It’s modular, and includes a wire stripper, crimper, and cutter, engineered for working with data cables like the Ethernet cables you may rely on every day to get fast, reliable internet. And if you’ve been splicing together ethernet without something like this, chances are good that those connections aren’t physically stable. So quit doing a crappy job! Just buy the crimper and make your cable splicing that much cleaner.
