I have a hard time sitting on any discovery of a cool, versatile tool... I don't expect fanfare for posting this, as this tool is pretty simple. In one way, it's really just a pair of shears (shown below). But the differences are: the blades are some up-to-date stainless steel that hold a sharp edge; the handles are extremely comfortable; they're spring loaded, and you can squeeze the handles with your whole hand, allowing you to transfer more strength to the material you're cutting. Lots of applications around the homestead.
I paid $9 for mine (new) a couple of years ago, at a local hardware store - I've seen them more recently at the same price. I usually keep my unit in my mechanics tool box, since it's good for trimming gasket material, etc, and the tool has a notch for trimming light-gauge wire. It's actually been great for uses like cutting long lengths of thick corrugated cardboard (for mulch), cutting thick felt, cutting cord or plastic strapping, trimming the roots off of harvested garlic (does it better than pruning shears), harvesting 50 lbs of lavender flower stalks off the plants (ditto).
I abhor waste so I don't like blister-packed products, but I still acquire machine parts and other items that come in plastic blisters, and these shears are good for cutting into that stuff.
I used to wear a glove on my right hand when I used shears for long stretches with heavy material like cardboard. Wearing gloves isn't great when you suddenly need the dexterity of your fingers to do something else for a moment. With this tool, because the spring re-opens the blades after each cut, unlike ordinary shears the tool keeps your fingers from getting rubbed raw - if you use it for hours on end. I've noticed the design of the shears also keeps your hand muscles from tiring out as quickly.
Could be other brands of similar design are avalable, I dunno... the brand I bought is Wiss and the model is called Wezsnips. The blades are quite sharp when you get the tool, and they hold a very good edge for a long time.
