Many, many years ago, when Ironmind first started producing hand grippers, they were known as “Silver Crush” grippers and I’m sure you can see why — chromed springs and brilliant silver handles. These grippers did not have the numbers engraved into the bottom of the handles, nor the distinctive band, and there were only three strengths available: #1, #2, and #3.
My friend Sarah found this cool old-time hand gripper in an antique shop somewhere in Michigan and snapped it up for a few bucks. – What a steal! There’s no date on this gripper but I’ve seen the design before in a lot of old magazines going back at least as far as the 1920’s. The one above is in mint condition (including the box) and still a pretty good challenge with all six springs. The Whitely Giant Power Grip was made by Moosehead-Whitely, Inc., in Hackensack, New Jersey.
Grip developers have always been popular and the “Victor Master Grip” is a good one from way back, about 1926 or so. It’s got progressive resistance through a full range of motion and you can adjust resistance by the number of springs. You’ll still see this design around today.
