I really like ur work! What's the benefit of the vinegar etch?
[/quote]it's my understanding and I might be wrong but, the vinegar causes the steel to oxidized with a dark Grey color, which prevents the blade from rusting where it's coated. After the vinegar bath I tempered the blade hoping it would make the oxidation more durable. It didn't work as well as I would have liked. But it looks real cool!!! And if you are doing the differential quenching it will bring out tHe Hammon similar to samurai sword
