These are amazingly well crafted shafts. It's straightness, even tempering, finishes and attention to detail push accuracy to the limits. 

Features:

• Manufactured in 17.4 PH rebored from bars certificated by steelwork; straight and smooth
• C.N.C. machined
• 3 backwards fins and one for preloading located at 60/90/120/360 mm from the bottom of the shaft.
• The fins are deburred and have no corners perfect both for dyneema use and for other kind of wishbones
• Fins are TIG welded and create a stiffening bridge on the shaft, increasing its ballistic performances.
• Thick barbs, very strong and mounted with a special pin, high strength d. 2.5 mm TIG welded in a very accurate way.
• The barb is very smooth and polished for fish integrity.
• The welded pin allows to maximum hold because the welding itself creates a reticular connection between barb and pin, avoiding the ovalization of the hole
• TIG welded penetration cone maintains accuracy and protects the flopper/pin from jamming
