Well, probably anyone skilled with a grinder could do it for ya. You'd probably just want to polish the clip again with a curved sharpening stone or sand paper.
As far as the law goes, I'm personally not sure I would worry about. Judge Lowell Bray has written a whole stack of articles for Blade magazine about the dirk & dagger laws in California, and reviewed actual cases. The courts once found a man guilty of carrying a dagger for having a Spyderco mariner. That's right, a blunt tipped sheepsfoot blade was considered a stabbing instrument. So your knife could easily be considered a dagger as it is now anyway. It doesn't matter whether it has one, two, or NO edges. (if you carried it locked open IIRC. The law has changed several times over the last few years.) However, by the same token, charges were dropped against a man who was found carrying a spike bayonet under his coat. Now, if a politician wants to say an object is designed or used for no other purpose than stabbing people, then surely a spike bayonet would fit their definition. But, the law was worded so broadly to include anything that could be readily used as a stabbing weapon, that judges decided
intent must also be considered. After all, the lawmakers surely didn't intend to jail people for carrying pens, right? The guy carrying the spike bayonet used it for his job to poke holes in drywall for running cable wires. No crime. Thus, if you are carrying your folder as a tool, you are legal whether it has two edges or not. If you intend to hurt someone, you would be charged for carrying a butter knife.
Also, according to
your state laws , the knife has to be "capable of ready use" as a stabbing weapon. I'm not familiar with the Companion, but if we're talking about a folder, then to be charged with simple violation of the dagger law, you haved to carry it locked open! (I doubt anyone actually carries their folder with the blade open in their pocket. it would pretty much defeat the whole point of carrying a folder in the first place.) So, everything I typed above may be moot anyway.
As I said, if we're talking about a folder, I wouldn't worry about it either way. But of course, the final decision is up to you. Just make sure it's an informed one.
