The only "commemorative" that I own is a Brusletto Telemark knife from Norway, now sadly out of production. I had intended to buy one from James Mattis who had carried them, but I never seemed to get around to it until it was too late. I had written to him of the heroic story of the Norwegian underground and the Nordsk Hydroelectric Plant in Telemark Fjord, one of the two sources of heavy water for the NAZI nuclear weapon project. The other was in Austria and was very much smaller, making a very much more limited quantity of this essential substance. When the Norwegian undergound sent word out to the Allies of the German efforts to maximize production of heavy water at Telemark, it went straight to Churchill and then to a group of physicists in America, including Albert Einstein, who realized immediately the consequences of this. Einstein sent FDR an urgent message that the NAZIs were working on a atom bomb and included some idea of what it could be expected to do. FDR set the Manhattan Project in train and then he and Churchill ordered the destruction of the Nordsk Hydro plant at ALL COSTS. The RAF tried an air raid with Lancaster heavy bombers using the "Dambuster" bombs developed to take out the dams in the Ruhr Valley, but the plant was built under a protective overhang which prevented these monster bombs from doing any damage. The RAF next tried a raid by low flying Mosquito attack bombers, but none made it through the German flak to the plant. Then they tried a Command attack, but the German mountain troops rounded them all up before they could get off of the nearby glacier upon which they had landed and shot them all. Finally, the British exfiltrated a number of local Norwegians and trained them to do the job then reinfiltrated them into the Telemark area. They did accomplish the task of putting the plant out of commission for the rest of the war, but at a terrible price in reprisals on the local populace, a price of which all had been aware from the beginning.
Brusletto did not make that knife specifically as a commemorative of that wartime action, but I bought it as such and intend to keep it as such along with a book that I have that tells the story.
