My first knife made out of a steel rod. It was a car spring long ago..I began by cutting an amle piece and straightening it and then a few weeks later began banging away on a make shift anvil till I got what I wanted. Used a Propane gas forge. All done free hand, without any measurements except my eyes. No electric tools used. Lots of sweat and time. I used hand files and sand paper to get the final results. sketched a number of patterns I thought might look good on the knife.
