In the 1930s, a Finnish knife with a wooden handle, much cheaper than the Scout hunting knife with heavier blade, became popular as a sheath knife with us (7th-9th graders). After we sharpened it, we would test its keenness by dragging it along a blade of grass. If the blade sliced into the grass easily, we were confident the knife was sharp. It was good for gutting fish we caught because of the slim, more pointed blade.
I haven't seen one of these knives for years. Perhaps their life span was short because of their lighter construction.
