When I Google "Himalayan Blades", I came up with the Kukri House that then mentions Himalayan Blades.
Do some research on the top Khukuri makers. I don't believe they are one of them.
The best seems to be Kailash Blades, Tora and Himalayan Imports.
With the many other companies selling these you often get thick blades, little tapering, poor heat treating and lesser quality. There is a whole industry over there making cheap tourist blades.
You'll be much happier with a quality product. Maybe someone else knows more about this.
