·       Handgrenade m/1918

During WW1 Sweden adopted the German M1917 stick grenade. It was designated m/1918 and it was used in Sweden even up to WW2.

Handgrenade fm/1933

This grenade exploded on impact with ground. 1930-1933 trials were made with different constructions. The military wanted to avoid the risk of having the grenade thrown back. For this reason greanades which exploded on impact were tested. 

Major G Mörners constructed a cylindric handgrenade., which exploded when it hit something.

The ignition was due to gravity. The two cylindrical parts came together and this caused the grenade to explode. This hand grenade was developed in Bofors by Major Morner. The designation was fm/33 (fm = test-sample).

1933 the government thought that there was no need for an army and the tests were closed. However 1939 the idea was brought back and it led to Handgrenade m/40.

Handgrenade m/1940

When the war stood before the door in 1939, the Swedish army lacked modern hand grenades. The test grenade m/33 was improved and developed. Hand grenade m / 40 consisted of two cylindrical parts which were joined but could move towards each other. This hand grenade was a blow-breaking hand grenade, i.e. it exploded after the throw, when it hit anything. In the hand grenade, there was a spring under tenshion with a striking pin for ignition. When the grenade collapsed, the two parts were pushed together and the firing pin snapped off and the grenade burst immediately. There was a safety wing that after the throw would be released. It could fall loose by mistake in the case of incorrect handling. When the soldier should throw the hand grenade, he had to hold his hand tight over the wings! If the soldier changed his hand, the wings dropped! The hand grenade could then burst at the slightest movement!

In addition, it was required that there were no branches or other objects in front when the hand grenade was thrown. The grenade then explodes too close to the thrower. This hand grenade was withdrawn and it resulted in that the Swedish army lacked explosive hand grenades at the beginning of the war!

Handgrenade m/39

Sweden bought the German M1924 handgrenade. 1939 there was severe lack of all types of arms. The defense forces managed to buy 350.000 stick grenades m/1924 from Germany. In Sweden they were designated Explosive hand grenade m/39 (Shgr m/39)

Hand grenade m/1939 (German m/1924) had an ignition fuze BZ24 that should burn for 4.5 seconds. To use the hand grenade, the lid in the bottom would be unscrewed. Then the porcelain ring was detached which, with a string, was attached to the lower part of the burner. The soldier would pull out this string and the fuze burner started. These 4.5 seconds before the explosion were initially considered a good safety time. It soon turned out to be too long time since there was a risk for the enemy to pick it up and threw it back. To avoid this, the soldiers should repeat "Today's News" when the burner began to burn before the hand grenade was thrown. There were reports about stick grenades which exploded immediately! There were rumors that these incorrect burners were made by the Germans prisoners in order to sabotage. These rumors and claims were never investigated

Again, the Swedish defense forces had no safe hand grenade! The Royal Swedish Military Authority (KKV) then announced a competition to produce a safe ignition fuze. The competition was between Bofors Nobelverken, Svenska Tandsticksbolaget and the Swedish Defense Forces (1943 converted to the Swedish Defense Forces Works - FFV). The ammunition factory Marieberg got the order, which was part of FFV. The German burner was copied, but they also had problems getting a smooth and safe function. It was at this stage that engineer Rolf Oström took part and later led the development work. In 1943, a burner had been produced which was shown to the Armetyg administration and the CCA, but with a lack of results. After various changes at FFV, their burners were approved. On July 1, 1944, Rolf Oström was commissioned to start manufacturing this burner at the Zakrisdal ammunition factory in Karlstad. This new safe and working burner with Shgr m/39 was called Shgr m / 39C
