Magnum is Böker's entry level line, and it exists for a simple reason. Not everyone wants to spend two hundred euro on their first proper knife, and a beginner should not have to buy something disposable either.
Magnum knives are made abroad to Böker specifications, which keeps the price down while the design and quality control stay in Solingen. You get usable steels, honest construction and a huge variety of shapes, from classic hunting knives to modern one hand folders.
This is the line to look at if you need a knife for the tackle box, the workshop drawer, the glove compartment or the scout group, somewhere you would rather not worry about losing it.
