Rob Allen 7mm Spear Double Notch Shaft

All Rob Allen shafts are engineered from ultra-tough oil quenched carbon alloy spring steel, tempered to 2100MPa, with tri-cut tips.

Rob Allen shafts are forged from spring steel, electroplated, and tempered, making them extremely strong and rust-resistant. The high carbon content of spring steel makes it a tough material that resists snapping and shattering while maintaining pliability under high tension. The low alloy content prevents the shaft from staying bent after flexing, making vulnerable areas like the tip, sear, and shaft notches fatigue-resistant.

Rob Allen shafts feature a crescent-type sear notch compatible with many brands of Euro trigger mechanism spearguns, a tri-cut style point, and a bottom-mounted flopper. The loading notches are smooth and accommodate line wishbones without fraying them. Shafts come with two loading notches spaced approximately 2” apart. Notched shafts will work with both open and closed muzzle guns.
