Description
The Benchmade 51 Morpho sets the benchmark for premium butterfly knives. Its D2 tool-steel blade delivers exceptional edge retention, while the skeletonized G10 handles keep weight astonishingly low for fluid manipulation.

Precision in Motion
Feel the balanced swing of titanium-lined handles as the blade fans open with effortless momentum.
Every flip is a statement—smooth, controlled, and unmistakably refined.
Forged for Mastery
D2 tool steel is hardened to 60-62 HRC, then precision-ground to a keen edge that endures.
G10 scales are CNC-milled for grip and lightness—an engineer’s approach to a classic form.

Knife Care & Maintenance
Keep your blade performing at its best. Rinse and dry after each use to prevent corrosion. Apply a thin coat of mineral oil to the blade periodically. Sharpen with a whetstone or honing rod at a consistent angle. Store in a sheath, knife roll, or magnetic strip — never loose in a drawer. For carbon and Damascus steel, wipe after contact with acidic foods. For folding knives, clean the pivot area and apply a drop of lubricant to ensure smooth deployment.
