Overview
The SPEC-M-ENG25-S pairs a high carbon steel head with a fiberglass handle in a lighter 2.5 pound build, sold as a single piece rather than part of a multi tool set.
Compared to a heavier hammer, the lighter 2.5 pound head trades striking force for easier control over longer use, while keeping the same high carbon steel and fiberglass combination for durability and shock absorption. That makes it a lighter option within the same material family rather than a different type of tool.
- 2.5 pound weight
- High carbon steel head
- Fiberglass handle
- Sold as a single piece
Who it's for
Anyone who wants a lighter hammer for extended use or lighter striking tasks, where a heavier head would tire the arm. Less suited to heavy demolition or driving large stakes.
