Spunjer, you magnet to Moro beauties....and I do mean
swords!
"Adeg" loosely translates into "hairs standing", or "hair standing on end" as allusion to the many straight lines found in the lamination pattern.
I agree with you completely that the sword should not be darkened further. The way you have it now is more likely to be the way it was seen my Moros in its day. Though Battara has shown us some nice examples of heavily darkened Moro blades, I believe those are generally anomalies to lighter etching, more typically done by citric acids. I think your's is truer to form as is.
I am not sure I agree with the assertion that the laminated blades are rarer than the twistcore examples....certainly this would not be true of the many examples I have seen. Of course, on the other hand, we would have to examine an ENORMOUS number of blades to make any such assertion credible.
