Measure the length of the backsplash area you wish to cover with the edging. Mark and cut the stainless steel edging, using the hacksaw and saw box.
Apply a bead of silicone adhesive to the underside of the stainless steel. Line up the edging and press it into place. Wipe off excess adhesive with rags.
Miter the corners on sections where the tile has exposed outside corners. File the edging with a metal file so the corners fit snug with no gap. Cut and fit your mitered corners before cutting your finished length, as the length may change during filing.
