Lost Surfboards by Matt 'Mayhem' Biolos, Official Online Store Australia. The Quiver Killer by Mayhem does exactly what it says it will, kill your quiver! Built off the popular Short Round, this board is slightly elongated with a slightly pulled in nose and a round tail. The Lost Quiver Killer is great in all conditions including knee-waist to double overhead. Use it as a single board quiver or as your 'step-up groveler'. Perfect blend of performance and stability for all conditions!
