They maintain an edge relatively well, though not as long as a pair of heavy Wiss scissors, when cutting thick sheets of very tough carbon fiber fabric, and the ease that they can be sharpened makes them invaluable as a go-to tool for cutting materials all day long

Astonishing sharpness, ease of cut, large size(cuts out that fabric quickly and makes the little tailor snips at the tip with no complaint and thats with the nut set very lightly.
