When it comes to wire, these flush cutters pack a powerful punch in a small, comfortable package. I was working on the underside of a deck that had numerous staples through it that were way too long for the application. Not only were the staples in the way, but it also only takes just a couple of them stabbing you in the head to get a real distaste for them. I had a pair of red handle Klein flush cutters that worked until i noticed i had completely chewed up the cutting surface - making them essentially useless for everything else. When i went on amazon to get another pair, I looked for another flush cutter that might be able to handle the hardness of the staple, but be easier to manage than a set of nippers.I found these, and immediately saw all the different sizes and wondered if i needed the biggest ones or would one of the smaller pairs work. After reading reviews, i landed on these and i do not regret buying them at all. Not only are they incredibly ergonomic, the cutting surface is apparently made of some steel that thinks its as hard as diamonds. The cutters made mincemeat out of the staples and left me feeling like the cutters were doing all the work - no fatigue. You feel like you should have a much larger tool in your hand than you actually do. You can see the cutting edge is still in perfect condition after cutting hundreds of staples that shredded my poor little Klein’s. These cutters are also shown next to the new pair of Klein’s. The Klein’s will always reside in my small tool pouch - they are too handy, small and inexpensive to not have a pair. Likewise these knipex cutters will always reside in my tool bag because they are a powerful tool in a relatively small package. It makes me want to try one of the larger pairs to see if they will cut nails - i would do anything to avoid having to tie both hands up with a pair of nippers.
