Overview
The Shark 21-2023 is a hammer built from alloy and high carbon steel, weighing 8.8 ounces with overall dimensions of 12 x 4 x 1.5 inches. It ships as a single unit.
At under 9 ounces, the total weight sits on the lighter end for a 12 inch hammer, which favors control over raw swing force. High carbon steel is a common choice for striking faces because it holds up against repeated impact without chipping as easily as mild steel.
- 8.8 ounce total weight
- 12 x 4 x 1.5 inch dimensions
- Alloy and high carbon steel build
- Sold as a single pack
Who it's for
Suited to users who want a lighter hammer for control-focused tasks rather than heavy demolition work. Less suited to anyone needing a heavy-head hammer for driving large nails or breaking material.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light 8.8 ounce weight reduces arm fatigue
- High carbon steel head resists wear
- Light weight limits force for heavy driving
- Grip material is not specified
Performance notes
The 12 inch overall length gives a standard swing arc, while the 8.8 ounce total weight keeps fatigue lower on repeated light strikes. High carbon steel in the head resists deformation from impact better than softer steel alternatives.
