Have you wondered: What is the hardest gripper? Where do my grippers lie? What grippers can I get to bridge the gap between what I am closing now and my goal gripper?
Questions such as these are why you have to join THE GRIPBOARD. Everything regarding Grip Strength has been discussed. If there is something that hasn’t, then you should bring it up.
In most cases, all you have to do is use the search function and you get what you need.
Recently, a member on the Gripboard, Sultan_of_Spin, dug up a gem of a thread, originally started by Stalwart Sentinel. Within the post was the succession of Grippers from the easiest, the IronMind Guide, to the toughest, the RBWT (Robert Baraban’s World’s Toughest).
Here is the hierarchy according to Stalwart Sentinel’s research. Take in mind that grippers with the same name can vary. For instance, due to changes made in spring material, the original Heavy Grips 300 I have is much tougher than the newer one I have. Still, even with variance in mind, this is an excellent list to base your purchases and training choices upon.

Remember, some grippers will turn out weaker than others due to inconsistencies in the manufacturing process, but this gripper scale is a very accurate guide to how grippers line up according to difficulty.
How well you keep them conditioned is also a factor. For years, I never cleaned any of my grippers, and because of this, they have gotten rusty which gradually makes them harder to close because the spring binds up somewhat.
As you can see, there is a variety of terms on this list. Here is a legend for all of the descriptors used.
The 3-place decimal number = spring size measured on a micrometer, expressed in thousandths of an inch.
RB – Robert Baraban Gripper
IM – IronMind Captains of Crush
HG – Heavy Grips Gripper
COC – IronMind Captains of Crush
PDA – Piedmont Design Associates (made and sold grippers up until about 2004.)
PDA285, PDA262 – These numbers dictate spring size. PDA sold their grippers by spring size. The numbers represent thousandths of an inch.
GM – Grippermania.com Certification Gripper (The number tells you the level)
N – Narrow. RB will make grippers with a narrow or wider handle spread.
BB – Beef Builder
Again, this information came from a thread started on the Gripboard by StalwartSentinel at this ADDRESS. I appreciate the effort he put forth in putting this list together.
Recently, there was an innovation put together by Greg Amidon and Dave Morton that tests the amount of weight needed to close a gripper, called the Redneck Gripper Calibrator. Click the link to read a .pdf about this device.
In the future, I plan to get one of these devices to begin rating my own grippers, but at this time I do not have any information to contribute about it. Look for more down the line.
