Stanley's are for carpets and plasterboard.
Good for leather, too. Anywhere you need to push the entire blade through a thick and stiff material.
But it's not a huge amount of jobs that can't be done as well or better with a $5.00 2-3" pocket knife. At least at a bench where you can resharpen when needed. I used to buy razor and exacto blades in bulk; 100 packs. Then one day I ran out and resharpened an exacto. Huh, whadya, know, it worked and was faster than changing the blade.
It's been many years since I had a boxcutter. I still use an exacto on occasion. But there are definitely a huge variety of bladed tools for any job which are purposely shaped for specific jobs and will last a lifetime. Instead of buying replacement blades for each one, you can keep a basic set of tools for shaping/sharpening them all. With a grinder and/or belt sander you can modify or make tools for specific jobs, even.
