I strike gold in rivers without taking a step. I sweep across a scene without moving an inch. I sit on a stove, held by a handle, shaping what you make. What single word connects them? What am I?

This manmade item is how humanity sees through walls!

I have a mouth but never speak, I have a bed but never sleep, I run for miles but have no feet, And I help the ocean stay complete.

A well-used bar, teenagers and people whose romantic partners get too close ask for this final frontier.

Weapon. Double edged. Straight to the heart. Up close and personal. Don’t give me that hostile stare.
