Ease Your Muscle Strain When Hammering

Posted March 20, 2017 12:00 AM by Engineering360 eNewsletter

A shock-absorbing hammer may reduce arm muscle strain and consequently reduce the risk of tennis elbow for users. This conclusion was reached by an engineering team from the University of Wisconsin-Madison after ergonomic testing requested by the hammer's manufacturer, Fiskars.

A good rubber grip will not only insulate the hand from the vibration in the handle but also provide enough friction that the user does not have to grip it as tightly to maintain control.

For those that use hammers regularly enough to actually get arm strain (eg- Tradespeople, etc) why not just go the whole hog and go for a pneumatic or electric driver or similar design that does the nailing with minimal strain and risk of missing the nail and injuring yourself.

A cheap version of the existing nail gun concept (eg- no self feeding magazine).

Good point, I think most tradesmen nowadays use a nail gun.

A quick pole shows that 6 out of 10 grad students don't know what a nail gun is. One even proposed a cellphone app was the answer.

Back before I had a nail gun or high powered cordless drills that could sink a 4 1/2" screw down to its head in hardwood I learned to hammer with both hands so that when one got tired I just switched over and used the other for a while.

And then when you get really tired, use both hands at the same time?

I can remember as a kid installing a ceiling in the basement. Hammering up will kill your arm in no time.

The methodology is not confidence inspiring. They used 20 volunteers, which from the video posted appear to be grad students with little experience holding a hammer.

The video of hammering suggests that what was measured in the 20 volunteers may differ significantly from someone with experience driving (even just hitting) nails with a hammer.

If this hammer is marketed toward people embarking on their first and likely last project, the research may be spot on.

.

The quote near the end is very telling...

".... These results definitively nailed down the benefits of the shock-absorbing hammer, providing further justification for Fiskars to move forward with their product and opening the door to future collaborations with UW–Madison. -..."

.

Results designed to open doors.

Kind of like golf clubs.

It has to be clubs design fault not the fact that the persons using them are just bad at golf for any number of reasons.
