During World War II, the F-1 Limonka was the Red Army's hand grenade. Although it has long since ceased production, it can still be found in all sorts of crisis zones.
Our 3D-printed F-1 Limonka is completely harmless and purely a decorative object. It looks great on your desk or in your EOD collection.
The detonator can be unscrewed, and of course, you can also pull the printed cotter pin. The F-1 is delivered with the detonator removed, and is well-padded for transport.
Of course, it can also be used as a means of representation in exercises, but it will not survive frequent throwing.
