I'm not really assuming anything.
Also I think talking about prisons is not very helpful as that's a subset of society that have already shown themselves able to ignore laws.
I think two things have to be accepted.
Violent crime will always be with us no matter what laws are put into place.
(Even if all knives were banned someone would sharpen a spoon.)
If everyone was able to carry any fixed blade legally then there would be an increase in knife violence. (Some people who would otherwise not be able to, would be too easily provoked/tempted into pulling out their knife)
