How do I present a idea for a new tool?

Question

I would prefer it be made in the U.S.A. It is for gardening.

Answer 1

If you have the bucks and your trusted friends think there is promise, go to a patent attny to get the ball rolling.

If you are more relaxed about it, contact some garden tool houses and disclose the idea. You may not get compensation, but you have the satisfaction of inventing something new and seeing it implemented.
