I have the second such set. I build barns to make a living, so I need shears that can withstand abuse. On average, for all the metal I cut daily, I use scissors for a few months at most. I've tried them all, Wiss, Milwaukee, Midwest etc. The only ones that come close are Lenox but they rust very easily. Each of these sets has served me well over a year on average and the quality of cut is the best I've seen. They don't rust much and the only thing I ever did to them was spray some silicone on the spring to loosen it up. All in all, I'm no expert, but I've used a lot of scissors over the years, and for me, this is the best I've ever had.
