| 1 | # Mash Monster | 1 | Mash Monster grippers are associated with The GripBoard's certification ladder. The name covers historically distinct equipment: the original Warren Tetting-made certification grippers, retail examples made for training, and the later system of rated grippers supplied and controlled by Cannon PowerWorks.[^1][^2][^3] |

| 5 | Gripperpedia is collecting reliable information about this gripper brand or model, including its manufacturer, production history, specifications, photographs, and contemporary sources. | 5 | The original certification ran from **2003 to 2023** and used ten levels of unique grippers made by Warren Tetting. Its preserved site remains the primary reference for the legacy equipment and certification history.[^1] |

| 7 | The original project's history describes commissioning a gripper above the IronMind No. 3 level. Tetting made three prototypes, which were sent to experienced gripper closers for evaluation. The aim was a controlled challenge based on designated grippers rather than an athlete's own example of a retail model.[^1] | ||

| 11 | Mash Monster-named grippers also reached private collections. Joe Musselwhite's February 11, 2012 review documents his newly acquired **MM8, MM9 and MM10** grippers from Gripper Superstore.[^2] | ||

| 15 | A privately owned training gripper should not be confused with the designated gripper used for an official certification attempt. A model name or replica label does not establish that a gripper was one of the original certification instruments. | ||

| 17 | ## Later rated equipment | ||
| 18 | |||
| 19 | The later Mash Monster website describes a limited pool of grippers supplied, rated, qualified and controlled by Cannon PowerWorks. Its numerical level labels, such as MM160 and MM200, belong to this later system rather than the original MM1 through MM10 ladder.[^3] | ||
