 produced and exported large numbers of his grenade all over Europe. Apart from new types of explosives, trench mortars, airplane bombs and land mines he also created several inventions for civil use, but it was the development and production of arms that would bring him his greatest honours.

Just prior to World War I Aasen developed a powerful anti-personnel mine, "the automatic soldier," meant as a weapon of deterrence. The invention caused great enthusiasm within the French military but did not see production before the war. During World War I Aasen was given the task of producing hand grenades for the French army. He would have 13 factories with 13,000 employees working throughout the war.

In 1917 his hand grenade was finally adopted by the Norwegian army, who later promoted him to premier-lieutenant for his efforts. Throughout his life he received a number of honorary degrees and awards, as well as medals, for his inventions. Most notably he was made an honorary colonel in the French army, and a Chevalier in the order of the Légion d'honneur in 1915.

Aasen's fortune was greatly reduced as a result of bad financial speculations, and because he had never patented the rights to several of his inventions. He died from tuberculosis
