At 2.94 inches open and 1.63 inches closed, the Bug fits on a keychain, disappears into a coin pocket, and cuts with an authority that genuinely surprises everyone who picks one up for the first time. The G-10 Bug takes the proven Bug platform and upgrades it with a G-10 fiberglass composite handle and 12C27 Sandvik stainless steel blade — a meaningful step up from the original Bug's entry-level steel that brings genuine edge retention and corrosion resistance to the world's smallest Spyderco folder. No lock — the slipjoint mechanism keeps it completely clean, completely legal everywhere a folding knife is permitted, and completely in keeping with the Bug's identity as a keychain instrument rather than a dedicated cutting tool. The Trademark Round Hole opens it one-handed without a nail nick. The full flat ground blade slices with precision far beyond what 1.27 inches of blade length suggests is possible. Available in Red, Blue, and Black G-10 — three expressions of the same exceptional instrument, each carrying the full Bug G-10 specification without modification. This is the Bug for the naturalist, the estate steward, and the field professional who understands that the best knife is the one that's always there — and nothing is more always-there than a Bug on a keychain.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\"\u003eScientific Engineering\u003c\/h3\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e12C27 Sandvik Steel — Genuine Field Grade:\u003c\/strong\u003e The G-10 Bug's blade is crafted from 12C27 — a Swedish stainless steel manufactured by Sandvik and widely regarded as one of the best blade steels available at its price point. With a chromium content of 13.5% and a carbon content of 0.60%, 12C27 achieves a meaningful balance of edge retention, corrosion resistance, and ease of sharpening that significantly outperforms the 3Cr13 steel of the original stainless Bug. A genuine upgrade in a genuinely small package.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFull Flat Ground PlainEdge™ Blade:\u003c\/strong\u003e The 1.27-inch blade is full flat ground — a geometry that produces a thin, consistent taper from spine to edge across the blade's full width, maximizing cutting efficiency and reducing material resistance during slicing tasks.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSlipjoint Mechanism — Non-Locking:\u003c\/strong\u003e The Bug G-10 uses a slipjoint mechanism — a traditional, non-locking folding knife design that holds the blade open through spring tension rather than a mechanical lock. This makes the Bug G-10 legal in virtually every jurisdiction that permits folding knives and eliminates the mechanical complexity of a locking system in a knife this compact.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eTrademark Round Hole™ One-Handed Opening:\u003c\/strong\u003e Spyderco's signature round hole allows smooth, reliable one-handed deployment without the traditional nail nick — a meaningful usability improvement on a knife this small where a nail nick would be nearly impossible to use effectively.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eG-10 Fiberglass Composite Handle:\u003c\/strong\u003e The handle scales are injection-molded G-10 — a high-pressure fiberglass laminate that provides superior strength, dimensional stability, and grip texture compared to standard FRN.
