Rough Rider Classic Carbon Sheepsfoot (not 'Wharncliffe)
My only criticism is that the blade does not sit centrally when closed; in fact, it almost fouls on the liner on one side. Otherwise, it feels well put together with a solid half stop and I particularly like the serrated nail nick. It is a 5th of the price of a 'top-end' pen knife I have recently bought but it is far more than a 5th of it's quality. Not everything made in China is of dubious quality and not everything made in Germany is of top quality.
