Not a company, more a pattern

made by Otter nowadays as Jack already mentioned it above.
About Puma knives; their Puma Tec lineup is made in asia, but Puma IP is made (propably) in Spain and Puma Solingen is made in Solingen. The same with Böker; their Böker Solingen lineup is from Germany, Böker Plus is made in Asia and Böker Arbolito is made in Argentinia.
There are the smaller companies, that still are working and making great knives - beside Otter and Hartkopf - there´s Diefenthal, Klaas (aka Kissing Cranes), Schlieper (aka Eye Brand Knives aka Friedrich Olbertz), Hubertus, Hirschkrone, Kneissler, Linder, Richartz (their older knives were very nice ones), Robert Herder, Tina Messer... these are just the companies that come in mind when talking about traditional knives made in good ol' Germany. There are more others out there, smaller ones and ones that make only modern knives. I had to make some brainstorming

(I tried to keep in alphabetical order)
As you can see, there are still a lot of cutleries left that make still knives in Germany. Some make the overseas, but that´s just the minor number. Here comes Herbertz, Haller Stahlwarehaus etc in mind. They let their knives make in asia or somewhere else.
Hope that helps a little.
