When the striking surface of your splitting hammer wears out, there's no need to worry! This replacement attachment from Fiskars is specifically designed for the SAFE-T X39 splitting hammer model as well as the SAFE-T rotating splitting wedge. Over time, attachments naturally wear out. To avoid having to purchase a completely new hammer or splitting wedge, this attachment is available as a spare part. It can be replaced as needed. This Fiskars replacement attachment features a sturdy striking surface, is made of polymer, and is encased in a metal ring, providing added durability. The striking surface dampens vibrations that occur when the hammer strikes the wood. This damping results in fewer material splinters, which in turn increases the lifespan of the attachment. The weight of this replacement striking surface is relatively light at 300 grams. The diameter of the entire striking surface is 6.5 centimeters. Sturdy replacement striking surface made of polymer with a metal ring for the SAFE-T rotating splitting wedge and SAFE-T X39 splitting hammer. Color: White / Silver. Material: Polymer / Metal. Manufacturer's part number: 1001616.
