After numerous occasions of misplacing tools, finding tools I had forgot I had an not being able to remember why I have a small number of screws in a plastic bag in a drawer I have taken the following approach
(1) Label items using 3M 20 60 tape
(2) Purchase a small A-Z note book and make a list of items /tools You can then look at the book to refresh your memory( or you could use your computer)
(3) If anyone borrows a tool consider asking them to hold the tool against their chest and use your mobile phone to photograph them
Son.. No dad I did not borrow your drill driver
Dad.. Yes you did I have a photograph of you holding it which is time date and location stamped
Additionally I have set up a file on the computer called house In this file I store information for each room in the house
Eg bathroom
A short summery of how to replace the tap cartridge and a link to the replacement part
This file will also help the wife when I pass or can be given to a future owner of the property
