Overview
The SE 8399-RH-ROCK is an alloy steel hammer with an integrated alloy steel handle, weighing 21.27 ounces, built in the one piece style common to rock and geology hammers.
The RH ROCK naming and the one piece alloy steel build, where the handle is the same material as the head, both point to a rock pick style hammer rather than a standard carpentry hammer. That construction is a known choice among geology and prospecting hammers for its durability under repeated striking on stone.
- One piece alloy steel construction
- 21.27 ounce weight
- Rock hammer style
- SE brand
Who it's for
Suited to a rockhound, geology student, or prospector who needs a durable pick for breaking rock samples. Not the pick for finish carpentry or delicate work, where a lighter, cushioned handle would be more comfortable over long use.
Strengths and trade-offs
Drawn from this product's published specifications.
- One piece alloy steel build resists handle breakage
- Sized for rock and mineral fieldwork
- 21.27 ounce weight balances swing force and control
- No cushioned grip for extended comfort
- Not intended as a general carpentry hammer
Performance notes
A one piece alloy steel construction, where head and handle are a single continuous piece, eliminates the weak point where a wood or fiberglass handle meets the head, giving it more resistance to breaking under the repeated shock of striking rock.
