Knife leather case 4.0523.3 for SwissTool, Hunter and others.
Fits knives with a maximum length of 111 mm and 1-4 layer tools.
E.g. 0.83xx - 0.90xx and 1.34xx - 1.79xx.
Some pocket knives, such as SwissChamp 1.6795, fit but are a little too short so they go down a cm in the case. If you want a narrower case than the original for SwissChamp, this is an option.
