Ensure you get your own Non Disclosure agreement signed by any company you allow to see your actual design, if it's innovative and not obvious and you don't want it copied.
Most of what you show are forged metal, machined in some way to finish, and with the wood shaped to fit in, metal removal is not a good choice for production of such items unless the resale value is high (look at the size of rectangular metal block to make it from, everything else has to be machined away whilst being able to hold it firmly enough to machine it).
