Greg...I live in Charleston. I've not heard of Grisword. Can you provide any info for me to check them out? I'm assuming they do retail sales.I love cast iron, I have several vintage pieces from Griswold, Wagner, Birmingham Steel, etc. and I also have enameled pieces from Le Crueset, Staub, as well as pieces from the new generation of makers such as Finex, Field, and Smithey. Hands down the best combination of quality and value today is still Lodge, made in South Pittsburg Tennessee.
Having said that, my favorite vintage brand is Grisword and my favorite brand from current makers is Smithey, made in Charleston, SC. In full disclosure, the Smithey folks are friends of mine, but their cast iron is top notch (but Lodge is still a better value).
