Hi Moose,
so from what I understand, you've ordered a black Epoch but you didn't receive it yet - and I just assume that this would be your first SF?
Because I also heard about the sharp edges before placing my order and had some concerns.
Since the Epoch design is rather flat / linear, I don't think that would be as irritating.
The ring grooves at the choke point could be a little irritating, but I just got me some O-Rings for my saber today (similar design at the grip section, see below), and they're pretty much taking care of that issue.
Aside from that, even though my saber is much more "edgy" than the Epoch, I didn't find the edges to be problematic for me. It's really mostly where there's friction involved (e.g. when spinning).

After:
So maybe just check it out when the saber arrives and see how you feel about it . But I definitely recommend the O Ring approach (also adds a little more grip to the hilt).
