When I have had a beard in the past, when I was ready to shave it off I would use a trimmer first before I used one of my straight razors. Today I only used my Filarmonica straight razor, and the razor simply obliterated the beard. I have seen YouTube videos of guys shaving their beards just with their straight razors, even though mine wasn't as long as theirs. Now I must admit, besides having a truly sharp razor, I also did a true barbershop shave prep first to soften the beard. Hot towel over lather, Proraso Pre-Shave Cream, lather again.
