I can only speak to the quality of service and other products you get from some of these places- most of which are very high. The problem with asking knifemakers about buying pre-shaped and finished blades is that none would know... they probably would all make them themselves!
Again I'd suggest calling any of these places and asking personally about the knives. Say you want an honest opinion and tell them your concerns. Any knife place I have called with questions like these have been 100% honest and helpful in their answers. These places should (and probably do) know their products.
