Spyderco Manbug Wharncliffe MBKWS – Serrated Keychain EDC Pocket Knife
Spyderco's Manbug® packs full-size cutting performance into a body small enough to ride on a keyring, and the Spyderco Manbug Wharncliffe MBKWS is the version built for people who cut a lot of rope, webbing, packaging tape, and zip ties. Its full-flat-ground VG-10 stainless blade uses the wharncliffe profile — a perfectly straight cutting edge running to an exceptionally acute point — so pressure stays on the material instead of rolling off a curved belly.
This particular model carries a SpyderEdge™ fully serrated edge in an uncoated satin finish. Those scalloped serrations bite into fibrous material immediately and keep cutting long after a plain edge would need attention. The blade is housed in a lightweight injection-molded black FRN handle with Spyderco's Bi-Directional Texturing for grip, backed by a reliable back lock. At 0.7 oz and 2.5" closed, the Spyderco Manbug Wharncliffe MBKWS disappears into a coin pocket, a keychain, or a glovebox kit and is made in Seki-City, Japan.

Frequently Asked Questions
Is the Spyderco Manbug Wharncliffe MBKWS serrated or plain edge?
The Spyderco Manbug Wharncliffe MBKWS is the SpyderEdge™ fully serrated version with an uncoated satin blade. Spyderco also builds plain-edge and black-coated variants of this knife, so check the model code if you specifically want one of those.
What is a wharncliffe blade?
A wharncliffe blade has a completely straight cutting edge with the spine sloping down to meet it at a fine point. On the Spyderco Manbug Wharncliffe MBKWS that means consistent edge contact along the whole cut and a very precise tip for opening packages and picking out stitches.
How do I sharpen the serrations on the Spyderco Manbug Wharncliffe MBKWS?
Serrated VG-10 is sharpened from the flat side using a tapered ceramic rod that fits inside each scallop. Work the Spyderco Manbug Wharncliffe MBKWS one serration at a time, then strop the flat back of the blade to knock off the burr.
What steel is the Spyderco Manbug Wharncliffe MBKWS made from?
The Spyderco Manbug Wharncliffe MBKWS uses Japanese VG-10 stainless steel, a cobalt-bearing alloy known for a fine grain structure, good corrosion resistance, and an edge that takes a very keen finish — well suited to serrations.
How does the back lock on the Spyderco Manbug Wharncliffe MBKWS work?
A spring-tensioned rocker bar in the spine of the Spyderco Manbug Wharncliffe MBKWS engages a notch in the blade tang when it opens. Press the release in the middle of the spine to disengage and fold the blade. It functions the same in either hand.
Can I carry the Spyderco Manbug Wharncliffe MBKWS on a keychain?
Yes. The Spyderco Manbug Wharncliffe MBKWS has no pocket clip but includes a lanyard hole, and at 0.7 oz and 2.5" closed it is designed specifically for keychain, coin-pocket, or backup carry.
Is the Spyderco Manbug Wharncliffe MBKWS legal to carry?
With a 1.91" manually opened blade, the Spyderco Manbug Wharncliffe MBKWS sits under the length limit in the large majority of US jurisdictions. Some places restrict serrated edges specifically, so verify your local rules.
Where can I buy the Spyderco Manbug Wharncliffe MBKWS?
