Since we've gotten onto the topic of blacksmithing, a couple videos I thought you might find interesting.
First up, video from a blacksmith shop in Nepal where they mass produce Khurki knives. A practical, proven design for a big ol' chopper, made with the most basic of hand tools.
And, Man at Arms, a look inside a 'modern' weaponsmith's shop. Lots of powertools - the power hammer is especially cool.
These are movie and video game designs, but the tools and techniques would work for more practical designs. There's a couple dozen of these videos and other every week or two - some of the weapons are more practical, some are not, the process is interesting to watch for all.
