Yeah no edge , it's meant to be super cheap and catch free for pure jib.
from stepchild site :
This board was built to be destroyed. Unlike most jib specific boards, the street recession has no metal edges. This opens up more jib terrain like wood and aluminum rails where steel edges will catch and rag you down the stairs. With a tip to tail wood core construction this board can take the beating its given. This deck is designed for urban specific for the streets. Keep your mountain board fresh and let the Street Recession take the beating from the streets.
It's not something new though , Forum street dweller in 2005 i think and Burton dominant slick around that same year had a similar concept with edges only on some parts of the board.
I wouldn't use that on any slope though
