Product Description

The Benchmade Partial Immunity 2950BK-2 is a compact automatic folder built around M4 high-speed tool steel — a 1.95-inch black-coated drop point, green anodized aluminum handle, and push-button automatic deployment in a package small enough to carry in jurisdictions where blade length is a primary restriction.

The blade is M4, an ANSI high-speed tool steel with high vanadium and tungsten content. M4 is not a stainless steel — it delivers extreme wear resistance and edge retention significantly exceeding standard stainless production steels, at the cost of requiring regular oiling and drying to prevent surface oxidation. M4 will rust noticeably faster than D2 and far faster than stainless alloys if carried in wet conditions without maintenance. The black coating reduces corrosion exposure between sessions but does not replace proper care. Buyers who maintain M4 correctly will find the Partial Immunity holds a working edge for an unusually long time relative to its compact size. The 1.95-inch blade keeps the Partial Immunity below the two-inch threshold used in many automatic knife restrictions. Green anodized 6061-T6 aluminum handle scales are compact, rigid, and corrosion-proof.

Note: Automatic knives are subject to federal and state restrictions. Verify your local laws before purchasing. Ships same or next business day from Knifeworks in Columbia, Louisiana.

• Blade Steel: M4 high-speed tool steel, black coated — ANSI M4; extreme wear resistance and edge retention; NOT stainless — requires regular oiling; will surface-oxidize without maintenance
• M4 vs. stainless: M4 holds an edge far longer than standard stainless production steels; tradeoff is aggressive rust if not oiled regularly; black coating reduces exposure
• Blade: 1.95" drop point, plain edge, black coated — sub-2-inch format for carry-restricted environments; automatic deployment at any blade length still requires state law verification
• Mechanism: Automatic (push-button) — push-button deployment; confirm single-action vs. double-action at benchmade.com/products/2950bk-2
• Handle: Green anodized 6061-T6 aluminum — compact rigid frame; corrosion-proof anodized finish
• 1.95" blade advantage: Stays below 2-inch thresholds in jurisdictions that restrict automatics by blade length, not mechanism alone
• Dimensions: 4.62" overall, 2.67" closed, 1.74" edge length, 0.105" blade thickness, ~2.05 oz
• Warranty: Benchmade LifeSharp warranty — free lifetime sharpening, blade replacement, and mechanical repair
