Blade hardness

[dld]

Are the Tibetan short Sword, Fighting Tarwar and Butterfly Sword hardness is the full blade length or like the Khukuri just one spot the belly?

In response to a similar question, ndoghouse previously wrote,
"I see hardening nearly the full length of the blade but that may vary depending on Kami as well. In other words six inches from the tip of the blade is probably harder than six inches from the handle."

...if you look at the hamon on a used blade then you can tell they are definitely concentrating on the "sweet" spot but that spot is not as localized as on a Khukri. I see hardening nearly the full length of the blade but that may vary depending on Kami as well. In other words six inches from the tip of the blade is probably harder than six inches from the handle.
