Yep. The plunge groove variation Adam mentioned is BARELY discernible at a glance but makes sense of a small mathematic/geometry anomaly that (in my opinion) Hero makers have struggled to resolve. New reference (I’m afraid I can’t share) highlighted it just enough to make the informed change and cross verify over what we’ve already seen.
Similarly with the pommel it’s a surface anomaly that is visible across references but just needed a very specific angle to make sense of it. It is VERY subtle.
The biggest change that will be noticeable is with the interpretation of the hole in the pommel (we’ve actually leaned into what DaveP discovered there… which does mimic what we believe is going on in the emitter) and the addition of the rough machining marks in between the cube valleys (a distinctive “wart” noticeable mainly by the tri ring)
Overall, the hilt remains exactly the same and will be largely indistinguishable from its predecessor in batches 1-3
