Hi All! I'm new to this site but have enjoyed reading many posts. I'm wondering if anyone has info on the steel used in the two knives I've seen on the Khukuri House website. They show a 5" and a 6" belt knife. I assume it is probably old spring steel like the khukuris but I don't know. Any thoughts on the durability, edge retention etc..would be greatly appreciated. Thanks in Advance for any info you can provide!
