I would never have guessed, looking at photos posted about the place, given his interests and so on, that Buzzbait wrote copy for an advertising agency for a living. Even by that standard however, I have to say "...the material that holds the universe together in some sense of viable cohesion." is rather astounding.
Look to be serious, of course this is subjective. At the same time though, the fact that something has been used for centuries only says so much. Meaning it has sentiment and/or tradition attached to it, or something like that. But what it does not say is - that is the way it should always be. If it were, you wouldn't own a car.
Just about anyone who uses grips for anything where fine motor skills are called for - tennis, golf, archery, shooting, whatever - will be bound to agree that the substances used even ten years ago are not as good as those available now. In cases where resilience is added in, as it is with a knife, that applies twice over.
There might well be 'romance' in Stag, at one with nature and all that, but that is up to the individual. Even then, I'd prefer Mammoth Ivory myself, if I were inclined that way. In any event, on a bald usage basis, nothing else, no way stag can compete with modern man-made materials.
That doesn't mean Buzz's and the DeFreet's knife aren't attractive. They are. Doesn't alter the rest though.
