An unconventional design from Benchmade, the 5400 Serum uses the AXIS® dual-action mechanism - the knife can be opened via thumbstuds or using the AXIS automatic action.  This knife is recommended for EDC use, law enforcement or military personnel.

 

The Benchmade 5400 Serum features a 3.47" modified drop point blade made of 154CM stainless steel, hardened to 58-60HRC.  It is available with either a plain or partially serrated edge, in either Satin or BK Coated Black finish.

 

Black Machined G10 Handle scales ensure a solid grip despite environmental challenges.  

 

Reversible, tip up pocket clip included.
