Well...if you get into a survival situation big blades can come in handy.
For example. You are shaving and an earthquake causes near total destruction to your home and you are trapped in your shave den with only your mug, brush, the towel wrapped around your waist, and your 7/8++. Thank The Lord! You can use that mighty blade to chop your way out of the structure, and later to dress the game you took using your other survival skills.
I cannot tell you how many times it has happened to me
I do love the aesthetics of a big blade...and I really appreciate the fewer distractions (fewer rinses)
