The Ontario company produces high-quality cutlery for the military, law enforcement officers, and outdoor enthusiasts. The RAT-3 fixed blade knife is one of their mid-sized knives that is small for full concealment and large enough for most common cutting tasks. This model is suitable for everyday carry and for use as a hunting or survival knife. These Ontario knives have fixed blades that are made of 1095 steel. This is a high carbon steel that stands up well to hard use. It is quite strong and holds a very sharp edge. The company adds a black powder coating to give the blades resistance to corrosion and make them non-reflective. The blade on these knives is 3.5 inches long and .125 inches thick. The overall length of the knives is 7.8 inches, and they weigh 5.3 ounces. The Ontario RAT-3 has a tapered, flat ground blade. The tapered point is strong and gives you excellent control over cutting and piercing actions. The flat grind gives a smooth plane from the spine to the edge that helps decrease the weight of the knife. This grind also creates very little drag during cutting and slicing. The blade on this knife is the combination type. It is plain toward the tip and has a length of serrations toward the rear, which makes the knife more versatile, as the plain portion excels at slicing and push cuts. The serrated portion handles pull cuts. The blade also has jimping along the spine to give your thumb a firm purchase for greater control. The handle on this survival knife is made of waterproof canvas Micarta. On this model, the Micarta is a light khaki green in color. The handle has an ergonomic shape with a pronounced choil to keep your hand from slipping onto the blade. These are full tang knives, and the tang extends slightly beyond the scales to make the pommel suitable for hammering and crushing. There is also a lanyard hole through the end of the tang. The entire grip is held together with three screws for secure and dependable performance. This Ontario knife comes with a molded Kydex sheath that is Foliage Green. It is resistant to both water and scratches and is low-friction for easy sheathing and withdrawal of the knife. The sheath comes with two retention devices: a boot clip and a TekLok belt mounting system. The TekLok gear allows you to wear the knife in a vertical or horizontal position on your belt or attached to a tactical harness. You can also remove these extras and use the grommets on the sheath to hang it from a lanyard. If you are looking for an all-around knife to add to your hunting or survival gear, the RAT-3 model 8633 by the Ontario company may be for you. These knives have proven themselves worthy of use by the military and law enforcement, and they offer the same functionality to you. They are strong, sharp, versatile, and made of quality materials that will give years of service.
