Two-piece 9.5mm x 140cm titanium double flopper shaft

The two piece titanium shaft is a Grade 5 titanium speargun shaft engineered by Black Reef Co: Moderate weight, resistant to bending, and anti corrosive.
 
Even as a two-piece shaft bending strength exceeds standard 17-4 steel shafts, and the performance of the 9.5mm shaft is comparable to lightening speeds of a standard 7mm steel shaft's mass. Needless to say... it's fast. 
 
For use on Black Reef spearguns and similar mech designs (Ermes double roller, riffe, and others)

Hybrid Euro/American notch
