Spyderco Manbug 1.91" Wharncliffe Serrated VG-10 TiCN Black FRN Folding Knife

The Spyderco Manbug is one of the most compact lockback folding knives in the Spyderco lineup, engineered to deliver full-size cutting performance in a keychain-friendly package. This variant pairs a purpose-built Wharncliffe blade profile with an all-black tactical finish for users who want a small, discreet, everyday-carry cutting tool that disappears until it is needed.

The 1.91" blade is precision full-flat-ground from VG-10 stainless steel and treated with a non-reflective titanium carbonitride (TiCN) coating that boosts corrosion resistance and gives the entire blade a low-glare black appearance. The Wharncliffe profile is ideal for controlled push cuts, scoring, and detail work, while SpyderEdge serrations along the cutting edge bite aggressively into rope, webbing, and fibrous material with minimal pressure.

Measuring just 2.50" closed with an overall open length of 4.39" and a weight of only 0.70 oz, the Manbug slips easily onto a keyring, into a coin pocket, or rides discreetly in a pack. The black fiberglass-reinforced nylon (FRN) handle carries a textured surface for positive grip security despite the knife's tiny footprint, and Spyderco's signature round thumb hole allows smooth one-handed opening. A reliable lockback mechanism locks the blade solidly open during use, making this little Wharncliffe a serious cutting tool in a seriously small package.
