Ontario Knife Company has a long history of making high quality tactical knives and tools, including fighting knives and machetes that have seen combat in WWII, Korea, Vietnam, the Gulf War, and through to the present conflicts facing the United States. Measuring in at 13.625" the Chimera is a tactical fighting knife with a comfortable round Kraton handle, skull crusher butt end, and a 1095 high carbon steel serrated blade. Comes with a combination Kraton and Polypropylene sheath and is proudly made in the USA. Carbon steel knives are preferred by those who want a sharp, long-lasting edge. With use, a carbon steel blade will develop a distinctive dark finish. This is not a defect, but a natural result of the use of high-carbon steel. Carbon steel blades are not dishwasher safe, never let them sit in water for a long time, but rather hand-wash and dry your knives to avoid rusting.
