Spyderco Grasshopper™ G-10 Folding Knife | C138G | 12C27 Sandvik Steel | Keychain Slipjoint

The Experience

The Grasshopper is the largest member of Spyderco's insect family — and it shows. At 5.07 inches open with a 2.3-inch blade, it crosses the threshold from novelty into genuine field utility while still fitting on a keychain, clipping to a lanyard, and weighing just 1.4 ounces. The G-10 handle scales bring peel-ply texture and Torx screw-together construction to the classic Grasshopper platform — providing a non-slip grip from any hand position and field serviceability that the stainless version doesn't offer. The blade is 12C27 Sandvik stainless steel, full flat ground to a precise cutting edge that handles cordage, packaging, food preparation, and everyday field tasks with authority. No lock — the slipjoint mechanism keeps it legal everywhere, accessible to everyone, and perfectly at home as the knife that lives on a keychain permanently and handles everything that crosses its path. The Trademark Round Hole opens one-handed without a nail nick. The lanyard hole accommodates a keychain, necklace chain, or pack attachment. Available in Black, Blue, and Red G-10 — three expressions of the same exceptional instrument.

Scientific Engineering

• 12C27 Sandvik Steel — Full Flat Ground: The 2.3-inch blade is crafted from 12C27 — a Swedish stainless steel manufactured by Sandvik with 13.5% chromium content, heat-treated for an excellent balance of edge retention, corrosion resistance, and ease of sharpening. Full flat grinding produces a thin, consistent taper from spine to edge across the blade's full width for maximum cutting efficiency.
• Peel-Ply Textured G-10 Handle Scales: The G-10 fiberglass composite handle scales feature peel-ply texturing — a surface finish that provides a secure non-slip grip from any hand position including wet or gloved hands. The texture is more aggressive than smooth G-10 without being abrasive.
• Torx Screw-Together Construction: The G-10 Grasshopper uses Torx screw-together handle construction — allowing precise pivot tension adjustment and field serviceability with standard Torx drivers. A meaningful practical advantage over riveted or welded construction.
• Slipjoint Mechanism — Non-Locking: The Grasshopper uses a traditional slipjoint mechanism — holding the blade open through spring tension at the pivot area rather than a mechanical lock. Legal in virtually every jurisdiction that permits folding knives and completely accessible to users of all experience levels.
• Trademark Round Hole™ One-Handed Opening: Spyderco's signature round hole allows smooth, reliable one-handed deployment — far easier than a traditional nail nick, even on a compact knife like the Grasshopper.
• Chamfered Handle Edges: The handle edges are chamfered — eliminating squared-off corners that dig into the hand during extended use. A detail that separates a knife built for all-day carry from one built to look good in a display case.
• Lanyard Hole: A generously sized lanyard hole at the handle end accommodates keychain attachment, necklace chain wear, or pack lanyard — providing multiple carry configurations without additional hardware.

Boutique & Conservation Values

• The Largest of the Insects: The Grasshopper is where Spyderco's insect lineup crosses from keychain novelty into genuine field tool — a 2.3-inch blade is long enough to handle real cutting tasks while still fitting on a keychain and weighing less than a house key. For the field professional who wants one knife that's always there and actually capable, the Grasshopper delivers both.
• Three Colors, One Standard: Whether you choose Black, Blue, or Red, the specification is identical — same 12C27 Sandvik steel, same full flat grind, same peel-ply G-10, same Torx construction. The color choice is personal. The performance is consistent.
