Both of these heavy-duty prospecting
hammers have tempered steel heads.
The True Temper® hammer head comes
with a wooden handle and is used for hard
(igneous and metamorphic) rocks; the all
steel Estwing® chisel head has a vinyl grip
and is used for soft (sedimentary) rocks.
Both tools also feature Estwing’s latest
technical innovation – the “Shock
Reduction Grip”. Field tested for a period
of 2-years, this grip has been shown to
reduce vibration from impact by 50%.
