Carbon Loss During Folding

Hi guys,

I know there’s carbon loss during folding, especially multiple times, as in Japanese bladesmithing, but is there enough loss for it to be a concern? Kapp in “The Craft of the Japanese Sword” throws a number of .03% carbon loss per fold, so after 10 folds, a 1%C stock would retain .7% but the question is how does it relate to carbon loss in modern stock steel like 1095? I’m not taking other factors into account, like forge environment or oxygen exposure, only multiple folding.
