The pen is mightier than the sword and the symbolism is equally important. The pornographic one in the middle (a Diplomat) is the executive office equivalent of 35" tires - or an AK-47. It's designed to strike fear in the minds of subordinates and give junior executives "pen envy":

Like 35" and AK-47s, it says "mine is bigger than yours" and "mine holds more rounds than yours" - or - "mine will crawl all over you and get to the top of the hill first". The nice thing is that it costs less than 35s, never needs balancing, doesn't wear out and has traction in all weather conditions - although it does need rotating from time-to-time. It holds more rounds than an AK-47, is capable of slaying thousands with one stroke, never jams or freezes but occasionally it does need the magazine refilled - that's why serious combatants keep a spare in a shoulder holster. It was once the weapon of choice in executive circles - perhaps still is. I use mine every day, but not with the same zest as before I retired - now it seems more like target practice or shooting cripples.
