That's fair. While this isn't professional legal advice and I'm not a lawyer, I'd caution that while carrying a knife as a tool is legal, carrying weapons for the purposes of harming others ("self defense" falls under that here) falls under weapons possession laws in the Criminal Code. Here is what a "weapon" is under the Canadian Criminal Code:
You can see that's rather broad, but keep in mind the "mens rea" aspect of the Criminal Code. You generally need to be of a "guilty mind" in order to be charged with a crime, whatever frame of mind is necessary for whatever action is considered a crime. So yes, you can legally walk around with a pocket knife, fixed blade, machete or even a sword strapped to your hip, but you cannot have violent intentions with the item. You can be carrying it for transportation, employment, utility or recreational purposes, but if it's determined that you possess the knife for violent purposes, you can be charged. If merely suspected, you can have your item confiscated.
If it is determined that you are trying to hide a knife that is designed as a weapon, such as the "Shivworks Clinch Pick 2.0", and you are attempting to conceal the presence of the knife, then;
Note that the manner of carry and the circumstances surrounding an incident where such a knife becomes a problem will certainly factor in, and that merely obscuring a knife from sight (as in carrying a pocket knife inside a pocket), isn't necessarily considered "concealed".
TLDR; Not legal advice, but if you are carrying a regular knife designed as a tool, it shouldn't be a problem. Things become more problematic when the knife is designed as a weapon (or even marketed as one, as that can signal intent in carrying it).
EDIT TO ADD; There is also an understanding that if you happen to have an item with you, be it a knife or otherwise, as a tool, and you need to rely on that item for self defense, you are permitted to meet the force presented to you; that is, you can defend yourself with items at hand using "reasonable force".
