Cho Facts
One of the unique aspects of the knife's design is the notch at the base of the blade, just above the handle, called a cho. There are many stories and a few facts surrounding the cho. The practical reason for the cho is to prevent blood or tree sap from flowing onto the handle, which could cause the user to lose his grip on the knife. Another benefit of the notch, as many khukuri do not have pommels, is to prevent the user from sharpening the handle of the knife while honing the blade.
Cho Traditions and Legends
The notch has two religious significances for Hindus. First the notch itself represents the Hindu fertility symbol. Secondly, there is an inset in the cho shaped to represent the hoof of a cow, which is a sacred animal in the Hindu faith. Legends also say that the notch was developed to enable a fighter to catch the blade of his enemy during hand-to-hand combat.
Cho Myths and Falsehoods
There are also many falsehoods spread about this notch. One of the more common is that the notch is designed to allow the owner to safely cut himself so as to never sheath an unblooded knife. This would not work, as the notch is not sharpened. Another myth is that the notch is used as a sight, to enable accurate throwing of the knife. The khukuri is not a balanced knife and would not be an effective thrown weapon. The notch is also not a can opener. There are drawings of khukuri more than 1400 years old that clearly show the notch.
History of the Cho
The oldest known khukuri blade, on display at the National Museum in Kathmandu, has the cho. Indian temple drawings dating as far back as the year 600 A.D. depict this distinctive notch at the base of the blade.
