Mechanics & Inner Workings
The journal is constructed in such a way that pages can easily be added and removed, allowing the notes to remain organised.
The pages made from film can be used to overlay information onto other pages.
This is often used for maps, where the map is drawn on a paper page, and different types of information, such as altitude or landmarks, are drawn on separate films for overlaying on the map.
The film can also work as an emergency fire-starter, since it is extremely flammable.
To prevent the entire journal from bursting into flames from a loose spark, it is often kept in it's protective Ramwolf casing.
In cases where the information is non-critical or the risk of fire is low, a leather pouch is often used in its place.
