Ga, most men are into electronic gadgets..Since it has to be under $20., how bout a case for his cell phone or a car charger..Also men always seem to want the latest new fangled tool that they will never use
Every man in this family wanted one of those self locking wrenches last year..Probably none of them were used, but they wanted them anyway
I would go to Lowes or Sears and ask the fella in tools what the latest tool fad is..
