I have carried Buck, SOG, Benchmade, Spyderco, and Kershaw.

The Kershaws wore out in a couple months. The other ones lasted. The Kershaws were 20 years ago. If they had not fixed that, they would not still be around.
The reason I am carrying SOG again, is I sometimes see and employee from the Lynnwood factory. He says the #1 knife that employees carry is SOG [duh] and the #2 is Spyderco.

There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self. -Ernest Hemingway
