I saw this question was answered in part here. But it only answered why it isn't used today. I understand both why it was used and, through this explanation why it stopped being used. On one hand, the stick provides the thrower an increase in range, and the reason it fell out of favour is because it was apparently too expensive and had logistical issues. But surely a more expensive grenade would at some point be used for more quality over quantity minded armies, right?
As far as I'm aware, literally no major standing army on earth uses stick grenades at all. That seems like a very comprehensive denial of the weapon system. Is there any more to the story than just "it's expensive and difficult to transport?" And if that's the case, what made the weapon system so popular with the Germans? Unlike with half tracks which came and went on both sides of the war and have since vanished on the modern battle field, the alternative weapon system, the standard pineapple grenade, was available, and derivations of the basic design we are all familiar with are the universal standard for soldiers to this day. I'm sorry if the link I provided is basically the entirety of the story, but it seems a touch anti climactic and feels like it leaves something out that I'm just not privy to.
So if you look at the main advantages of the stick grenade; longer throwing range and less prone to rolling away than regular egg-shaped handgrenades, you'll notice that these are made technologically moot by the emergence of initially the rifle grenade, and later the underbarrel grenade launcher. In combination with the poor personal ergonomics, the logistics of streamlined production lines in the late Second World War, and the relative labour intensiveness of production, the stick grenade became obsolescent very fast as soon as the Second World War started and rifle grenade applications became more widespread. As the Second World War wore down, and the arms race of the Cold War started and underbarrel, contact-fuze, grenade launchers emerged as viable options for infantry platoons its obsolescense was made complete.
