If your library has copies of John Masters's autobiography, you may want to read it. He was an officer in the 2/4th Prince of Wales's Own Ghurka Rifles un til 1947, when he emigrated to the USA to become a bestselling novelist.
He does mention khukri use, and his illustrations show the knives in use. He explains how a big khukri was used to behead a buffalo at Ghurka religious ceremonies.
He fought on the NW Frontier of colonial India, and in WW II in Iraq and in Burma, where he was promoted to Brevet Brigadier, and commanded the British stronghold codenamed, "Blackpool", where many a Jap met his Maker.
The autobio is in two volumes. Pre-war India is, "Bugles and a Tiger". Then, "The Road Past Mandalay". Quite interesting. Oh: Masters was awarded, among other medals, the Distinguished Service Order, just below the Victoria Cross. (This role is now filled, for battle honors, by the newer Queen's Cross For Gallantry.)
