Cut rounded corners into your travel documents and medicine blister packs
While there are many more effective ways of saving weight in your luggage — like leaving your petrified wood collection at home – shaving every last milligram off everything does add up. It is also satisfying and fun!
I have in the past removed a kilogram of weight from my packing entirely from things that individually would be considerd absurd. One such absurdity being cutting rounded corners into travel documents, medication packets, and the like.

Cutting round corners into printed-off travel documents doesn't just save weight — it also gives documents printed off at home a more official feel.
Cutting round corners into blister packs may seem silly as they already have rounded corners — but there are two good reasons:
If a blister-pack is already half-blistered, or you know how many pills you'll need for your travels, you can cut away the excess packaging. This saves weight but leaves a sharp corner that could cause injury or damage clothes. This is when you'll want to round the corners.
Corners can be more round.

How to cut rounded corners
Creating rounded corners with scissors is difficult, unless you're a pro your documents will look tatty.
A much better approach is to use a tool that punches the round corners in one action. Tools like this exist and can be bought off the internet.
While on my travels with some butchered documents, I found a tool that does just that. I brought it home — wondering how many corners I'd have to round to make up for the weight of the tool itself.
