Suitable for use

The knife arrived in a package that protected it well and on time. The knife itself has a moderately long blade, but sufficient for the type of use expected of it. The edge is well-made, it cuts wonderfully. The saw is sufficient and I think the wire cutter loses some utility at the back, but that´s a matter of taste. The only drawback I have is the handle, which seems sufficient but for my taste is a bit loose and thin, with its grip frankly improvable with a slightly thicker handle. The sheath is rigid and covers the blade well. The closing system is like those on backpack straps, which is usually secure. As almost always, the straps are designed for the leg or arm and not for the thigh, which is where I like to carry it, making it necessary to make one yourself or buy it. Overall, a very good knife for the price. We´ll see how it holds up to oxidation

Great for its quality-price ratio, even bigger than I calculated. The handle is plastic but the blade looks very good quality. I haven´t tried it yet
