I think having tools allows one to create many other things. Also, having the knowledge of how tools were used and created 100+ years ago can really broaden your knowledge. The more tools and knowledge you have, the more you will see chances to create arising from your own mind.

To suggest a specific thing to improvise, how does one know where to start? What are you trying to do, what materials do you have? ETC.!!!!!

Knowledge is the thing to collect. Imagination allows it to be applied in new ways.
