I'm looking at the wiki, trying to decide which bombs are worth using, and the Deconstructor I have certainly sends things flying, but the wiki says nothing about it having knock-back.

I look at 4* bombs and I'm trying to decide between Master Blast Bomb and Irontech, and I wonder does Master Blast Bomb really not have knockback, or is it an omission like with Deconstructor, or am I missing something else entirely?
(I already have a good Shivermist, I'm just trying to understand the blast series before I commit to anything)
