This one is pretty simple. The Piranta is a light (1.4 oz with blade installed, .15 ounces for each additional blade in the wrapper) folding knife which takes removable, replaceable blades. The blades are thin, and very sharp.
I’m far from a knife expert, but I like to think I know what I’m doing. I don’t own another knife that I can get as sharp as the Piranta blades when new. For making the initial cuts when skinning a game animal (or gutting a fish), nothing works as well as the Piranta. This is especially true with small, more delicate critters like hares, squirrels, and grouse. It’s now an essential part of my kit for small game hunting.
The downside is the delicate, disposable blades. You can delimb a deer with the Piranta, but you’ll need to be slow and precise to avoid breaking the blade. The blades do dull fairly fast; you’ll probably want to go through a couple while skinning and boning out a deer. They can be replaced with bare hands, but snapping the used ones out requires a bit of force. I’m a lot more comfortable using pliers, which is a problem given that I don’t carry a heavy, full-sized multitool in the field. Disposing of the blades is easy at home, aside from the questionable moral content. In the backcountry where to store still-sharp surgical razors is not exactly obvious. Cleaning the Piranta is also quite the nuisance. The blade design provides a lot of stubborn crevices, far beyond those found on a normal folder. After butchering anything larger than a squirrel a lot of boiling water and a toothbrush is required for full sanitation.
I anticipate keeping the Piranta on hand for day trips fishing and hunting small game, when extra blades need not be carried, as well as home butchering of any larger game. It likely won’t make the cut for backcountry use, or if so I’ll bring it with only an extra blade or two, and use it just for the initial skinning cuts. A larger, sturdier, and more comfortable knife is more expedient for a lot of the less delicate skinning and butchering large game requires.
