Abstract
A few students from previous classes created smart and creative tools that could be used anywhere in the world for many different applications. I took it upon myself to create a universal, ergonomic handle, and update those tools to interchange easily with my handle.
Bill of Materials
- Handle - 32g - 2.5 hours
- Pin - 2g - 15 minutes
- Pruning Hook - Based off Hannah Power's Pruning hook - 29g - 2 hours
- (2) Stanley Heavy Duty Utility Blades (10 for $6.14) http://www.amazon.com/gp/product/B0006HVTSO?keywords=heavy%20duty%20razor%20blades&qid=1449560989&ref_=sr_1_2&sr=8-2
- (4) 3MM nuts and bolts
- Cultivator Rake - Based off Matthew Andres' Hand cultivator - 66g - 5 hours

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
