Like Gawker, I was into sharp metal -- knives (got a huge collection since I can't buy firearms over here).

The catalyst was my electric shaver's batteries wearing out -- they were soldered into the unit. So, I either had to buy a whole new one, get the old unti maintenanced, or go back to a Mach 3. A straight razor at least tied back to my collecting/hobby of knives.

So, a year and a half in, and still going strong.
