I may be naive, but I don't think there is a human being alive that knows more about hand saws than Mark Harrell at Bad Axe Tool Works. He has acheived a level of saw geek-dome that is awe inspiring...and I say that with respect. Whenever I need saw info, I head to his site and surf through the hockey-sock of info there. Recently Mark made it even easier to parse out what you need.
Mark takes you through the steps of how to maintain your saw or completely rehab a vintage model. Mark is a prime example of my typical sign off - In order to understand, you must do. Mark has spent thousands of hours doing research, experimenting and testing everything from handle material to tooth patterns. If you have any interest in saws at all go here and get ready to learn. My buddy Mark is a fantastic teacher.
