 early on in my career, I had a client with just this amazing, beautiful stainless steel blade for a lawn mower and for that, calling it a prototype is like a finished product. And we did a patent search and it is devastating to find almost like a knockoff. You know, if someone had read his mind and it was his exact idea, this prototype cost about $8,000. The nice things I like about the way Matthew works at prototype houses, they initially not always jump in to a full functional working model. At that cost, there's ways to do things. Injection holding.
