This is an everyday tool used to avoid direct contact with door handles and physical buttons. Over the revisions I've narrowed on a few key features.

The round feature at the back of the tool is for the index finger during use and, when not in use, hanging from a belt loop for easy access.

The extended feature on the bottom of the round is to protect the middle finger from slipping forward and allow more control of the tool when pushing.

The middle triangular feature is to strengthen the part when pulling or pushing, a straight feature is too thin and likely to snap. The opening in the middle also adds more continuous perimeter layers which also increases the rigidity of the part.

The front hook feature is slanted to aid in pulling handles. Also, at the very front is a small flat, roughly the size of a fingertip, to be used for push buttons.

The engraved stripes on the front hook increase rigidity further by adding more perimeter layers, but their primary purpose is to denote the dangerous side of the tool. The striped section is for interacting with the possibly infected environment and the smooth sections are for the user to touch.

If you have further ideas for this tool, please let me know. You can see from my picture that I've been slowly improving on the idea over the last few weeks. I do however have limited testing because I'm adhering to shelter-in-place as best I can. Any input would be greatly welcomed.

Stay safe out there y'all.
