A pocket-sized metal slider with a shark emblem set into the face. The shuttle runs on magnets, so it snaps from end to end with a clean click rather than a rattle, which is the sort of quiet repetitive motion that keeps hands busy during a long call.

It is machined rather than moulded, so it has the weight that plastic sliders never manage while still sitting flat in a coin pocket.

• Machined metal body with a raised shark emblem and wave detailing

• Magnetic shuttle with a firm, clicky stop at each end

• Weighted enough to feel solid, small enough to carry every day

• Available in steel, blue, black and bronze finishes

• Quiet enough for an office desk, a lecture hall or a waiting room
