Try drawing on paper with pencil. That way you can play with the lines more readily. Graph paper helps with dimensions. Mess with the design until you just can't stand it and have to make the knife you've drawn.
Designing is as important as the making. Design takes years of study to begin to get it right.
Of course you can just copy another design, which is really fine. Do that too. But most of the fun in my mind is designing, and then realizing it in your knife.
I say it takes years because you really can't know starting off what will actually work in a knife and what will not.
And every component of the knife design has trade offs and compromises. Knowing what you want the knife to do is a big part of understanding the complexities.
Then knowing what design options are available to you.
Then learning how to execute those options.
It's a long road to a great looking and functioning knife, but a really enjoyable journey. Make knives to learn how. Study their use to learn why.
