any knife with an automatic spring or other device for opening and/or closing the blade, commonly known as a switch-blade knife.
This is a pretty vaguely-worded law (compared to switchblade laws in other jurisdictions). There is a difference between "automatic spring" knives and "spring-assisted" knives, so it's not clear whether a "spring-assisted" knife would fall under the statute. It would depend on whether the spring assist mechanism falls under the "other device" part of the law.
We then turn to the courts and the common practice in the Maryland criminal justice system to determine how persons are charged when they are found in possession of an assisted-opening knife that is not a switchblade. I argue they are charged under the switchblade law.
Just like persons driving a stolen vehicle are charged under the livestock law.
In DC, entering a dwelling, at night, with the intent to commit any other crime, is Burglary I. Unless it's a houseboat. Then it's always Burglary II. Why did they write it that way? Beats me.
There are nuances to criminal law.
