I have an obscure one that is at the top of my own list.
Samek, the guy can bend leather and mod a knife like nobody's business.
I'll add pluss one's to Thombrogan, Clyde Stump, Morimotom, and most of the rest of the folks already mentioned.
There are also a couple of guys that will get me to open a thread if I see they started it or posted on it, Gravelface, Mymindisamob, KAAK, Unclehammy, Progunner,
I do have a couple of knifemakers, or steelartists, as I would prefer to call them that I keep an eye on, Stag&Steel, Bailey Knives, and I just found one that only sells on the board once in a great while, because his stuf is spoken for way to fast for it to go up for sale, J. Neilson.
I know that there are many more that deserve mention, but I have a short attention span and not much experience.
Oh I also check on what thegratenate has posted, as I have a tendancy to forget once in a while.
