Spyderco Manbug MPCBL – CPM SPY27 Steel in a Keychain-Sized Folder
The Spyderco Manbug MPCBL packs Spyderco's exclusive CPM SPY27 powder-metallurgy steel into a folder small enough to live on a keychain. Developed with Crucible Industries, CPM SPY27 supercharges the cobalt-enriched chemistry of VG-10 with niobium, nitrogen and added carbon, molybdenum and vanadium — delivering an exceptional balance of edge retention, toughness, corrosion resistance and easy sharpening.
The 1.96" leaf-shaped blade is satin finished, full-flat ground and PlainEdge, paired with a lightweight fiberglass-reinforced-nylon handle molded in the distinctive cobalt blue that marks Spyderco's SPY27 family. A proven back lock and the signature Round Hole make this one of the most capable EDC pocket knives you can carry at just 0.7 oz.

Frequently Asked Questions
What is CPM SPY27 steel?
CPM SPY27 is a powder-metallurgy stainless steel made by Crucible Industries exclusively for Spyderco. In the Spyderco Manbug MPCBL it adds niobium, nitrogen, carbon, molybdenum and vanadium to a cobalt-enriched base for excellent edge retention and corrosion resistance.
How long is the blade on the Spyderco Manbug MPCBL?
Spyderco lists the Manbug MPCBL blade at 1.96" (50 mm) with a 1.75" cutting edge. The 2.5" figure sometimes quoted is the closed length of the Spyderco Manbug MPCBL, not the blade.
What is a leaf-shaped blade?
A leaf shape has a gently curved belly tapering to a fine, centered point — the profile used on the Spyderco Manbug MPCBL. It balances slicing, piercing and general utility better than a straight or heavily curved blade.
How does the back lock on the Spyderco Manbug MPCBL work?
A spring-tensioned rocker bar seats into a notch in the blade tang. To close the Spyderco Manbug MPCBL, press the exposed bar in the middle of the spine and fold the blade back into the handle.
How do I sharpen the Spyderco Manbug MPCBL?
Despite its high-performance steel, the Spyderco Manbug MPCBL sharpens readily on ceramic rods or a guided system. Match the factory bevel and finish with light alternating passes to remove the burr.
Why is the handle cobalt blue?
Cobalt blue is one of the signature handle colors Spyderco reserves for its CPM SPY27 models, so the color on the Spyderco Manbug MPCBL tells you at a glance which steel is inside.
Is the Spyderco Manbug MPCBL legal to carry?
With a 1.96" blade the Spyderco Manbug MPCBL sits under most local blade-length limits, but knife laws vary by city, state and country. Confirm your own regulations before carrying.
Where can I buy the Spyderco Manbug MPCBL?
You can buy the Spyderco Manbug MPCBL at Going Gear, an authorized Spyderco dealer, with full factory warranty support on every knife we ship.
