Since the formation of the EU all patents are now under one authority. I have tried to use their web search engine to find exactly the sort of patents you are asking about. Unfortunately, my attempts are futile and frustrating. There is something I am not getting, but the results are always worthless. I guess, I should start trying to pry that information out of the American patents

Pete...If you could narrow it down at the US patent office, there will probably be a European classification number to cross reference...But I won't waste my time on such a pursuit...I've been searching for years for any related patent to the venerable Belding & Mull without success. There are more dispensing and metering threads than I can view. The machinery patents that you seek could be buried in any number of classifications with all the various sub-catagories or threads. Could be in a winding thread, could be in a seam welding thread, or it could be in a manufacturing process thread. It's probably in several threads. But who knows...you might get lucky by patent searching the names of known makers of damascus/twist steel. If that doesn't work, it's going to be hard row to hoe. Maybe Gaier's book will offer some search names...Bob
