Here are several examples of WWII German made tool knives or combination fighting knives. Puma and at least one other company (trade mark “S”) made these variants. The handles’ materials may be constructed from early plastics, wood, and even antler (Stag). The circled area in the picture on the right is an area, which usually cracks from shrinkage on the plastic handled variants and should be inspected closely when contemplating a purchase as it will obviously affect value/pricing. The pictured Stag handled "S" trademarked variant is from page 149 of The Military Knife & Bayonet authored by Homer Brett. I don't own one of those yet;-)
