Design Tip for newbies

[Crayola]

I designed a chef's knife today. I drew two versions of it and made cardboard models. I tested them side by side and got another person to play with the models a bit to see which one they liked better. We both chose the same model. I also rocked both models to the end of their tip and compared them side-b-side. Designing 2 models and making 2 cardboard versions to test side-by-side was very useful! I learned a lot about kithen knife design that way today.
