Nail Nippers
The rolling-head pincers that pull nails and staples without damage — or nip stubborn fasteners flush and drive them home.
When you're starting a nail next to vinyl or plastic trim, keep your thumb against the surface right beside the nail — a missed hammer blow lands on your thumb instead of the material. Your thumb heals; the vinyl doesn't.

A hammer that glances off a nail head leaves a crescent dent in whatever sits behind it. In framing lumber that's cosmetic; in vinyl siding, a J-channel, or plastic trim, the dent is permanent — there's no filling or sanding it out, only replacing the piece.
That's the whole trick: your thumb occupies the spot a glancing blow would hit. In the words of the crew member who taught the creator: your thumb will heal, the vinyl won't.
