Spyderco Manbug SE 1.91" Wharncliffe Folding Knife

Spyderco Manbug SE: Precision in Your Pocket

Don't let its diminutive size fool you. Spyderco's Manbug SE is a serious cutting tool disguised as a keychain companion. This is a knife that punches well above its weight class.

Blade Design and Performance

The heart of this knife is its 1.91-inch Wharncliffe blade, a profile that combines the cutting authority of a straight edge with the precision of a scalpel. The full-flat grind maximizes edge geometry for superior cutting performance, while the fully serrated SpyderEdge cutting surface handles tough materials with authority.

Crafted from VG-10 stainless steel—an elite blade material known for edge retention and corrosion resistance—the blade receives a non-reflective titanium carbonitride coating that reduces glint and enhances durability.

Handle and Ergonomics

The injection-molded fiberglass-reinforced nylon (FRN) handle features a bi-directional texture pattern that provides a secure grip in wet or dry conditions. The matching black-coated lock bar and hardware maintain a cohesive, professional appearance.

Practical Features

• Back lock mechanism for reliable blade retention
• 4.39-inch overall length when open—compact enough for keychain carry
• Keychain-ready design without sacrificing cutting capability
• Fully serrated edge for aggressive cutting tasks

This is the knife for those who understand that serious tools don't require bulk.
