The Kershaw Cinder Copper 1025CUX is small and formidable. The clever design allows you to have a good three-finger grip on the handle.
You open the 3cr13 stainless steel blade with the thumb stud. Once opened the liner lock ensures that the blade stays in place. With your thumb on the spine of the blade you have enough control over the blade. This version of the Cinder is enhanced with a copper handle. A tough material that starts forming a patina after some time. As such each knife will be unique.
The spacer on this pocket knife, designed by Rick Hinderer, has also been enhanced with a bottle opener. We can conclude that the Kershaw Cinder is an asset to any bunch of keys.
