Fabrication and Metalwork

Crafting with a mix of materials is where my rapid prototyping skills seem to flourish. In these trades, I make attempts at inventing, and reinventing products that will serve me in other activities. My dad always says "Don't try to reinvent the wheel", I respectfully (albeit defiantly) disagree. Why wouldn't you try to reinvent something, reimagine it, redesign it? Sure it was a great idea, but everything can be improved.
