Same company but the every man.
For everyday use and abuse I also carry this Gerber utility knife. They are super slim and the blade is replaceable.
My wife left me unsupervised one day I used an old battery charger and some acid for cleaning concrete stains. With some old copper pipe scraps I coated it with copper because the coating came off. The coating lasted a long time . But the spring got weak and would open slightly in my pocket. Not good with a razor blade so it got retired to the old knife box.
