Shock or vibration absorbing hammers

 

Maddison Wisconsin U




Fiskars isocore XXL 22oz 16"

Damping ratio from Stanley, handles only:


Stanley fatmax anti-vibe Xtreme

This is newer version which goes back to single forged steel body,and eliminates the hammer head bolt+resin, which is said the head loose after just weeks of use

I am a union carpenter and i purchased this hammer from Lowe’s. Used it for 3 months, i loved it great balance, very light, sinks nails wonderfully, magentic

 holder worked beautifully, great vibration reduction. But alas flawed design makes the head come loose. Amazon reviews are all the same. Even a coworker purchased one as well, same deal.

Toolguyd, amazon


Triple plastic injection (similar to sport shoes soles)

Fatmax Xtreme:



Toughbuilt 拓必得 shockstop 20oz ,22oz,24oz (two times or more expensive than 木井方/SATA)


木井方 low vibe(2017)手柄藏有減震彈珠







SATA has similar bolt and spring design(german patent?), but spring is hidden inside the body, not easily seen

Quick trial at shop,but the grip found too rigid, and hardly notice any shock absorption.

豬仔嘜 是fake,沒有彈弓/彈珠!!!

With fluid piston:





16 inch

Swinging a hammer can lead to  tendinitis in the elbow like that seen in “tennis elbow.” , or carpel tunnel syndrome
