For those who have interest in the subject ( deserves its own thread) , all details are on this link:
" Interesting data. The only grippers available in 1991 from Ironmind were the 1,2,3. ...A much harder,larger similar looking item to the 3.. What would you have "called it"?. Remember the official #4 was not available until several years later. Of the 41 grippers PDA randomly tested for me (John Syzmanski) doing all calibrations of mine and others that day. It seemed like a well thought out digital device that held the grippers straight and tested in inch pounds the closing force to shut the gripper on the end of the handle. The Phantom was randomly checked 11 times that day and never varied but a few inch pounds. Several number #4 "of the day" were tested with lower readings. Grip stalwarts Rich and Tex the only 3.5 official certified gripmen I know say(without knowing what it was) the Phantom is tougher than the 3.5 s they have felt or closed. I did purchase a Calibration device from Chris Rice and asked him first to check that it was functioning properly. I tested a few recent #3s and they were very uniform right at the 150 mark. (We checked the weights used in the calibration as well) My old 527#3 I first certed on was in the low 160's and the Phantom around 186 as I recall but I didn't bother to retest it. The #4 we have here which just scares everyone away (even Rich and Tex was a very high number of 224) I did the testing to gain some personal knowlege no more no less. I would be glad for Chris to come by any time and re check my findings as I know him to be a fair and just man. I am very pleased with the fit finish and accuracy of grippers today they are a fine tool. The grippers I shut are real, the standard of what was available at the time and are a part of the evolution of grip history.Thanks for everyone's thoughtful insight . RS "
