The Custom Pena-Song is a collaboration between designer Jared Van Otterloo and custom maker Enrique Pena. This is the pentacle of high-end Balisong blades, executed with Pena's renowned fit, finish and attention to detail. This version comes with a hand-rubbed satin, CPM-154 blade, blasted and hole-milled titanium handles and a custom Steel Flame Skull pocket clip.

Brand new, direct from Enrique Pena, USA.

Blade: The clip point blade is made from American CPM-154 stainless steel with a beautiful, hand-rubbed satin finish. The blade rides on micro bearings for smooth, solid operation. If you can bring yourself to use this knife for cutting, the shallow hollow grind and Persian-style trailing point swedge offer exceptional slicing and piercing performance. Either way the stainless blade should require minimal maintenance.

Handle: Blasted matte gray titanium slabs form the foundation of this large butterfly knife. Contoured for comfort the handles are milled with chamfered holes that offer good traction when you need it and give the knife a perfect balance for cycling when paired with the blue anodized spacers at the ends of the handles. A titanium latch with steel pin at the end of the handles secures the knife in both open and closed positions. Satin titanium hardware completes the construction.

Carries via a custom, Steel Flame Skull pocket clip. Includes Pena embroidered zipper pouch for transport and storage.

CPM-154: CPM-154 is a particle metallurgy version of 154CM that benefits from the refinement in the PM process providing it with an increase in toughness and easy of finishing. CPM-154 takes a very fine edge and is highly corrosion resistant. Edge retention is going to be on-par with CPM S30V while being easier to resharpen. A great all-around blade steel.
