Like where you are going with
#87 as we are going for a cleaner more corporate logo, while keeping with the samurai Katana theme, albeit in the abstract.
if you look at the handle of antique samurai katana's, there is a very specific "weave" pattern that forms the diamond....can you play with a single diamond logo that mirrors the "weave" that crates it on the sword handle. Please let me know if you are not familiar with what I am referring to. An example can be found here:
