Here's a few write-ups I did awhile back on knifemaking. The first one is on how to make a fixed blade knife out of 1084 steel - included heat treating. The second one is on how to make a liner lock knife and focuses more on designing and fitting a folding knife.
Here's the one to the fixed blade knife: http://www.instructables.com/id/Knife-Making/
And the one for the liner lock: http://www.instructables.com/id/How-to-make-a-liner-lock-folding-knife/
Goodluck and let me know if you need help on cutting the blanks, filing bevels, heat treating or quenching 1084 steel, filing lock faces, pinning the knife, or more!
