Do-It Pyramid Mould.
Pyramid sinkers, as the name suggests, are moulded in a pyramid shape, with a wire eye on the square end.
They don't roll, so they hold bottom well where current or wave action are prevalent.
An excellent surf lead to use when the seabed conditions are too rough to use wire grip leads.
This mould is easy to use and produces 1 x 5oz & 1 x 6oz lead with each cast.
Leads require size 2 brass wire eyes.
