Ridgid Aluminum Pipe Wrenches, Alloy Steel Jaw, 18 in

I am a professional pipefitter. On my side work l use the pipe wrenches l inherited from my dad who used them for his side work. My dad inherited the wrenches from my grandfather who used them too. Never have these wrenches ever failed. It just occurred to me these tools could be 100 years old. The still work perfectly. The company l work for buys new Ridgid pipe wrenches as the company grow and gets more work. There is no differance between the appearance and quality of the new wrenches when compared to the old ones. Granted, some of the old wrenches had new jaws replaced by my dad about 50 years ago, but that was an easy fix and unexpensive.
