Great question. I really don't know, maybe the Gems thought that since it was the first procreation of a Gem, genetics and stuff might give Steven a new weapon rather than the same. And, they were surprised because he summoned it at a young age, like 12 years. Maybe they thought when he was an adult, he would summon it.
