I think the idea that his blades all share a similar shape mainly applies to his midtechs, probably because he doesn’t produce all that many models. The VECP and Talos are his most popular, and both have Rockeye DNA. The MK3, Myna, and Eagle have different blade shapes, but they’re much less common.
If you’re looking for more variety in blade shapes, his customs offer plenty of options: the Valmara, Hydra, Harpy, FM-1, Rockeye, M3, and Sicario all feature distinct designs. By the time the month is over, I'll post one of each.
