"Location: Durban, South Africa"
That's definitely working against you.
You have no idea the volume of email begging for, or attempting to steal our $ that comes from there.
I believe that many or most USA makers would drop the conversation on that alone...
...the phrase "CONUS only" frustrates many
Hey, South Africa is not Nigeria, actually think of all the great makers from SA that are pretty well known in the States: Andre De Villiers, Arno Bernard, Andre Van Heerden and I am forgetting many more...
Anyway, what I learned during the rather short time I have been collecting custom knives (all your fault in the first place, Mark

) is that no two makers work the same way.
Some makers have great websites, which reduces the need for exchanging e-mails back and forth to figure out what model you want.
Some do not have websites at all but will go to great lengths to understand what you really want. I have been dealing with one of the aforementioned South African gentlemen and he has been sending me drawings of what he thinks corresponds to my needs on a regular basis. It might lengthen the order process, but then I feel that the knife I am going to get in the end will be uniquely mine.
Others do not even bother to answer e-mails, or if they do they soon lose interest when they feel that you are not interested in any of the knives they have readily available at the moment.
Finally, there are those very popular makers who are virtually unreachable for the average buyer but who run their own forum. There they will post updates about their work, WIP pictures, virtual shop tours and from time to time, if you are lucky, some of their knives will be posted for sale for the forum members.
In the end, with some makers you can really unleash your imagination, with others you have to take what they have and still consider yourself lucky.
Then there is the category of makers you cannot order from, either because their communication skills suck or because their order book is closed.
I try to avoid the former, for the others luckily we have exchange forums and dealers. Les Robertson has helped me get on the list for knives that I could never have gotten on my own.
