One of the BEST things you could do is hit the search button and do a search on Mad Dog knives in the archives. Don't search all open forums, but search the old general discussion areas. Let me explain.
There are some real long Mad Dog threads here. Some of the content is flame related. Ignore all of that. What I like about the Mad Dog threads, though, is you get A LOT of discussion on tang shapes, knife design, O1 steel, serrations, handle design, handle materials, etc. It is a good read! Ignore the fighting and enjoy the info. I learned a lot from the Mad Dog threads.
