Anvil has a robust lead core and a camouflaged outer sleeve and is so easy to splice in all sizes. Anvil is, to our knowledge, the most supple lead core available. It hugs the contours of the lake bed, aiding presentation and concealment as well as having extreme abrasion resistant qualities. A carefully created fleck pattern in each colour provides maximum camouflage. The high quality lead remains intact and won't break or split. A really superb and reliable product.
