No. 284

history

The hihistory of the Model No.284, originally designated as the Model No.144, dates back to circa 1915. The exact date is unclear. The model appears for the first time in the 1922 catalogue, referred to as a grafting knife. At that time, the bark remover was made of either horn or ivory and was fixed, ie it could not be folded in. The scales were made of fiber (Model No. 144) or horn (Model No. 144 ½).

The model remained virtually unchanged in its basic functions and construction throughout hihistory, except that the debarker became foldable and was no longer made of horn or ivory, but of a soft metal such as brass. The entire series of these pocket knives ended around the early 1950s. Very similar pocket knives for garden work were also produced, that of the 470 series.

functional parts

Model No. 284 had a cutting blade and a bark remover.

material thickness

Cutting blade: 2.5 mm; Bark remover: 1.6 – 1.8 mm

construction

Model no. 284 is a 1-layer pocket knife. The head rivet fixed the cutting blade, the foot rivet the bark remover. Both tools can be opened from the front. The center rivet fixes the two identical scale parts. At times there was a notch on the front switch and the front circuit board to be able to open the bark remover better. There was always an intermediate layer of brass to compensate for the difference in material thickness between the cutting blade and the debarker

scale material

Horn and fiber were used as the scale material.

Liners/spacers/rivets

The liners were either made of brass or steel, the intermediate layers and the rivets were always made of brass.
