Ergonomic saviours that keep wrists and shoulders relaxed.
Swivel thumb scissors let your thumb follow the natural arc of each cut, which keeps your elbow down and takes pressure off tired wrists. If RSI, carpal tunnel or shoulder niggles threaten your week, a swivel becomes less of a luxury and more of a career extender.
The learning curve is real. Expect a week of awkward thumb placement while you break old habits. Also, swivels can loosen over time—keep a mini screwdriver handy and check the joint weekly. Finally, not all sharpeners are comfortable servicing swivels, so ask before handing them over.
