Hello everyone. I am looking for any information I can find about a knife maker named Joe "Dakota" Hawk and two of his sons. Jack Hawk and Ken Hawk. I met them at a gun show in Salem Virginia in the early 90s. I have about 30 of their knives and am looking to sell them but I don't know what they are worth or even how to get them appraised. I tried to upload photos but they are all over the 1MB limit. Any help would be greatly appreciated.
