Hey guys, I'm Andrew lucas, an Australian industrial designer and I'm currently in nepal working with Khukuri House Handicraft Industry on lots of fancy new things, ranging from suggesting new equipment to give the kamis a hand to new processes and new designs. I've been documenting the process with a whole bunch of videos and I think they're pretty interesting so I should maybe share them here. I thought there might be a better place for me to post this but I'm not a maker, nor am I actually speaking on behalf of KHHI. Also I can't really post this is the khukuri section of the forum as it belongs to Himalayan Imports and these aren't HI khukuris. If there's somewhere else that this should be, I'd love for a moderator to move it there.
But on to the knives. So far I've done a lot of stuff. First up was an improved heat treat. The traditional way of heat treating these khukuris involves heating up the blades to red hot and then pouring water onto the edge from a teapot. This means that they can "paint" the hardness on wherever they want, leaving a great differential edge quench. The problem with this though is that the hardness changes along the length of the blade and it's not very consistent. I absolutely adore the teapot quenching, but it's got a lot of issues with it and Saroj (the owner) wanted to have the ability to dial up the performance, quality and reliability. So as of a few weeks ago I started the process of teaching the kamis how to oil quench their khukuris and then give them a proper temper. I've got a few videos that show the process.
