3-Pack Knipex Cobra Pliers Set (180mm, 250mm & 300mm)

I've bought them all separately over the years as single deals and would gladly pay full price if I had to buy them again. These things are amazing, and probably spurred an unhealthy bias towards Knipex as I now own way too many of their products.

I miss the days not too long ago when I bought the rebranded 2 pack from Sears for $30 plus was able to use points!

By using the terms 'break' and even bringing up PVC pipe, you truly have no idea of what I'm talking about. Any conversation about Knipex isn't for those that likely use tools on a very light or infrequent basis and could 'get by' with a cheap pipe wrench, 1 adjustable wrench, and a hammer.
Knipex are for those that use tools on a heavy or frequent basis or those that want the utmost lifetime lasting quality where the tool performs just as well on year 50 as it did on Day 1.

The issue isn't one tool 'breaking' and one tool not. Nor has it anything to do with soft 'toy materials' like PVC.
For instance, I've used mainly top quality (and far more expensive, naturally) jawed wrenches/pliers that have such good quality and properly tempered steel, and machined sharply/precisely, that they grip your workpiece just as great after 30 years or so, as they did on the day they were new. That's what the extra money buys you.
What good are cheaper jawed wrenches/pliers, if after a few years of use they slip and slide on your workpiece, be it a steel pipe, bar stock, or whatever, and don't grip it with the 'bite' that's required for the tool to be effective.

I can guarantee you that the Doyles will have dull flattened useless teeth left on the jaws after even 10 years, as compared to the Knipex's sharp teeth after 10 years, if both sets were used heavily/frequently in the exact same way.

It boils down to... there's 2 different types of tool users, so it's wrong for each type to tell the other type what is the best tool for everyone or what's 'good enough'..
Harbor Freight and Doyles won't meet my needs at all for the performance and longevity that I expect out of my tools, while Knipex would be overkill and needlessly expensive for the majority of 'regular folks',
