Models No.288, No.289, and No.292 were one-piece pocket knives with a single non-bark stripper cutting blade. The model No.288 used the 2nd cutting blade of the model No.286, the model No.289 used the 2nd cutting blade of the model No.287, and the model No.292 used the main blades of the models No.285 - No.287.
The No.289 model is relatively common, while the other two models were only produced in small numbers. Apparently, the preference was to add a bark remover or a second different cutting blade.
These three models of this pocket knife series were manufactured from the late 1920s to the early 1950s.
Models No.288, No.289, and No.292 each had a single cutting blade.
Cutting blade: 2.2 – 2.5 mm
All 3 pocket knives are 1-layer models with a simple structure. The cutting blade turned around the head rivet. A brass spacer was used which is unusual as the back spring could have been used throughout. It can be assumed that it was easier to use existing components from the other models in this range for these 3 models.
Horn, fiber and possibly also Cellidor black for a short period of time were used as the scale material (cf. cat. 1952).
The sinkers, liner and rivets were made of brass.
