Information from the Spyderco catalog on the web

JBK:

"Take the 2-week Jester Test. Carry a Jester on your keychain, or in your purse or pocket for 14 days then on day 15 leave it home. You'll feel its absence. It offers ergonomic convenience; you forget it's there until you need a knife.

We've notched the blade's spine above the hole with crosshatching as a seat for the thumb while cutting. Another textured section sits on top of the snub nose so your index finger has guiding control over the fine tip. The blade is AUS-6 available in SpyderEdge or PlainEdge. Comes with a black, forest green, lime green or pink FRN handle molded with Volcano-Grip. Clipless. Discontinued Product - No Longer Available."
