Miller KS-1 Yellow Fiber Optic Kevlar Scissors, Easily Portable Utility Scissors for Working Technicians, Electricians, and Installers, Heavy-Duty Cable Cutters, 5.5 Inches

I've purchased these shears multiple times. I have red and a blue handled version which are both branded other manufacturers but are seemingly made in the same factory. As a low voltage technician, I dull many pairs of snips a year cutting and stripping various wire. These are properly hardened and sharpened unlike the ubiquitous free-fall snip most techs get a home depot. On copper wire, you likely wont dull this tool at all, but inevitably you'll end up cutting some shielded wire, T-grid, or other whathaveyous. When they are sharp they work great on fiber optic (as designed) but obviously bind up in weaves/string within cables when dull.I collect pocket knives and can say I have successfully sharpened a pair once or twice. One "blade" has very fine serrations to grip the cable, so you cannot sharpen it without removing those first. It's usually enough to just smooth out it's back side and sharpen the non-serrated blade. After a few sharpenings you may ruin the curve in the blade - scissors and shears have the blades bent inwards toward each other to maintain a pinch point. The screw that holds them together is easy to adjust, and the nut you see on the back side prevents your adjustment from changing.These will rust. They seem to be made with a good quality and affordable carbon steel, which is just not going to have chemical protection. If you're keeping them in a fiber kit to remain sharp just throw some lightweight oil on them from time to time.

Use these mainly for cutting paracord and other similar stuff. (No kevlar or other 'exotic' materials). Cuts well after substantial use, still sharp. The serrated blade holds the item and keeps it from slipping down the blade as the scissor is closed, so get cleaner cuts than an un-serrated blade. The scissors is a bit small, only room for a couple fingers, but this did not hamper its use in my case - no issue. The price $23 is very reasonable; paid more for other scissors that do not cut cord anything near as well as these.

Nice item. Very sharp. Cuts easily.

In my quest to find the ultimate computer workshop nippers, I bought this Miller Ripley cutter. I haven't used it lot but the prices was right and the cutters have a very fine serrated edge that make it the perfect cutting tool in the right situation. The quality appears very good.

Cut winch ropes easily.Wish I had this a long time ago.I will buy again

These snips are extremely sharp. They have no trouble going through the Kevlar thread in fiber optic cable. These are not meant for hands smaller than XL though (thus the 4 stars) a few of my splicers have small hands, and they can't operate them comfortably. Other than that, they're sharp and great for opening shielded fiber.

Micro teeth grabbed & blades cut well.Handel seemed a bit tight for medium-large size hands.It's worked well for me so far for cutting dyneema line, but I have not used it for very many lines so I don't know what the overall longevity will be.At this point it works well and is a good value.

The tension on these was spot on when I got mine. They snipped through 3k and 9k fabrics like a good pair of scissors through card stock. The best part was no fraying at all.Top drawer tool for sure.
