Sometimes I design knives by drawing them as fluid steel describes, other times I design knives with cereal boxes and a pair of scissors. I make and design mostly full tang knives doing stock removal, and find that getting the handle to feel right is a lot more difficult than figuring out what the blade will look like. I end up with a cardboard profile/template.
Regardless if they start out as a sketch or a cardboard profile, I scan them and redraw the profile so that I end up with a clear line drawing, black on white. You can see them
HERE. Lately I've been drawing designs for knives with rather narrow blades of 3/4 inch. It would not bother me is someone used one of my drawings to make a knife. Just because I drew it doesn't mean it has never been done before. Some of them are real stinkers and impractical because I was experimenting.
To print them out I place them in a WORD document and using the handy-dandy ruler at the top of the screen that shows the size of the text area, I can enlarge or shrink them to whatever size I want, usually making the handle the proper size and adjusting the blade after it's printed out.
I also trace knives others have made and play around changing different aspects of the design to see how they look on the computer screen at least. They can be seen
HERE. Some of them are from knives that appeared in the forum. Unfortunately I did not keep track of who made the original knife and can't give credit to the originator. I started out just collecting pictures of knives to stir my creative juices and to see how other more experienced makers made their knives.

Maybe someone else can say how they draw their knives???
