There are a lot of good answers. My favorite is "a mommy and a daddy knife maker".
It actually does not take talent, artistic ability, patience, or equipment.
Rick gave an answer that I never even thought of; "make a knife?" I've helped hundreds of folks make a knife and only two or three have become knife makers. It's the same as someone claiming that they are painters just because they helped grandma paint a room. I have written things but I am not a writer, for example.
When I lived in Vegas, I had a guy named Bob S. contacted me and wanted help becoming a knife maker. Over about a decade, he bought everything needed to make knives. He had four power hammers, six forges, a couple of grinders, thousands of dollars worth of handle materials, blade stock, guard stock, pin stock, belts, sand paper etc. He had a dream of becoming a world famous knife maker and selling a hundred knives at his first knife show. Even the idea of making knives filled his mind during his waking hours. He never made a single knife and never became a knife maker.
I've seen guys make a knife with two rocks, or two rocks and a scrap piece of steel and a camp fire.
We're getting closer, keep those thoughts coming.
Love and respect
