I'd bet half the people who use master links but refuse to buy the pliers that work well, make the job braindead simple, and can be had for less than $10 also own just one crescent wrench and use it for everything. "Hey, I've got a crescent wrench, and it works. I don't need to use the right stinking tool for the job. I know owning and using tools is part of being a man, but you know what's even more manly? Not owning tools, and using something else to half-ass every job that comes along!"

Fine. Everyone's going to do what they want, and that's fine. If they want to work on mechanical things but cheap out and not use the tools intended for the job then fine. It's not against the law. I used to be a helicopter mechanic in the Army, and I learned at the ripe old age of 18 while in school for that that one should always use the right tool for the job. Doesn't matter if it's a bike, a car, a helicopter, whatever. Everything goes much easier, and you tend to break fewer things, round off fewer nuts or bolts, and overall just save time and do a better job by just using the right tool for the job.

It's ten bucks for the tool. Just use it.
