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

Looking After Your Blade
Keep your blade in top nick. Give it a rinse and dry after each use to stop corrosion. Every now and then, rub a thin coat of mineral oil along the blade. Sharpen with a whetstone or honing rod at a steady angle. Store it in a sheath, knife roll, or on a magnetic strip — never chucked loose in a drawer. For carbon and Damascus steel, give it a wipe after cutting acidic foods. For folding knives, clean out the pivot and pop a drop of lubricant in to keep it opening smoothly.
