Great questions, the 3V is really the undisputed champion in terms of toughness, much more critical for the larger blades which are most likely woods and survival carries. S30V is a great all around steel, 3V is tougher.
The FFG are quite few because I believe a Sabre grind makes more sense for this application. The FFG's are significantly lighter weight, more than you would expect. The more bush craft type tasks like battoning really demand a slightly heavier blade, therefore most of the run is Sabre grind.
The Nimbus finish was determined during a Facebook contest in which I called upon the wisdom of people to name the new "accidental" finish. I was extremely pleased with all the suggestions and ended up choosing Nimbus. It means dark cloud in Latin which is not only reminiscent of the finish that was created but also the weather here in the NW for 8 months of the year

Very excited about this run of knives and to hear your feedback!
Thanks,
Brad
