They just got back from Knob Creek and are likely super busy, catching up after having been away a week or the like.
Email Garth, and when your turn comes up (which may take a bit) you'll get emailed by he or his assistant (Sammie IIRC).
After a series of several emails, which started in early May and finished in early July, I mailed several knives in on July 9th and await my turn...
IME that's the sort of time frame you're looking at, and with the show just having ended I suspect right now is just extra busy.
YMMV.
They do awesome work, and it's reasonably priced - it just takes a bit.
