That is a cool blade. I didn't know they were serial numbered... if all Randalls had been so identified so that we knew who purchased them and when, a lot of the mystery about old RMKs wouldn't exist.

Gurkha Khukuri
"The kukri or khukuri (Nepali: खुकुरी khukuri) is a Nepalese knife with an inwardly curved blade, similar to a machete, used as both a tool and as a weapon in Nepal. Traditionally it was, and in many cases still is, the basic utility knife of the Nepalese people.
The kukri is designed primarily for chopping. The shape varies a great deal from being quite straight to highly curved with angled or smooth spines. There are substantial variations in dimensions and blade thickness depending on intended tasks as well as the region of origin and the smith that produced it. As a general guide the spines vary from 5?10 mm at the handle, and can taper to 2 mm by the point while the blade lengths can vary from 26?38 cm for general use..."
