I want to point out that while you guys might pick a steel that's unique right now, nothing says that Darrel can't use that steel in some future order, or even if he thinks the Gunhammer line should move to that steel (doubtful, but possible). Yes, it's a forum sprint run and limited to, I dunno, 25 pieces or so, but if some other dealer wants to order a knife exclusive in the steel, I'm guessing Darrel would agree to that. What he won't do is offer the exact same configuration as the forum know, so your color choice should remain unique for example. But, you have to realize the nature of knife making is such that steels get upgraded over time. Perhaps, down the road, Darrel will find it necessary to offer "this" blade steel as a standard configuration.
The scenario is illustrated perfectly by the fact that he was allowing you guys to use CTS-XHP despite that being a 600 piece run.
