Are HI's non-kukri knives also zone-hardened as well?

Someone recently even polished one after descaling. It was very cool!

I think that HI swords have the edge hardened for all or most of their length. It depends on which part of the blade is intended for use. With the khukuris, it's mainly the belly of the blade. If in doubt about a particular blade, use the file test.

I remember that one ndog. It looked great with the hammer marks still slightly darker and the polish. Very unique look.

I second the vinegar solution. I started off using a 5 gallon bucket with Ph-Minus to take off scale, then philll told me about the vinegar trick. The single layer paper towel wrap works so much better and faster.
