| 3 | *This article is a stub.* | 3 | **IMTUG**, IronMind's Two-Finger Utility Gripper, is a compact torsion-spring gripper for working individual fingers, finger pairs and the thumb. It complements full-hand [Captains of Crush](/Gripper_Brands/Captains_of_Crush) training.[^1] |

| 5 | Gripperpedia is collecting reliable information about this gripper brand or model, including its manufacturer, production history, specifications, photographs, and contemporary sources. | 5 | ## Design and levels |
| 6 | |||
| 7 | IMTUG uses IronMind's GR8 steel springs and short handles with rounded ends, described by the manufacturer as “hemi-end” handles. It is made in the USA. The seven models run from **IMTUG1**, the easiest, to **IMTUG7**, the hardest. These numbers identify levels in this range, not poundages or Captains of Crush equivalents.[^1] | ||

| 9 | ## How it differs from a full-size gripper | ||
| 10 | |||
| 11 | The shorter handles permit targeted finger work. IronMind recommends using different strengths for thumb, ring-and-little-finger, and index-and-middle-finger exercises. Its instructions specifically recommend training the ring and little fingers together rather than isolating the little finger.[^2] | ||
| 12 | |||
| 13 | The rounded handle end also enables IronMind's **brush technique**: an additional finger lightly assists at the end of the handle to finish a close. The user can then hold the closed position or control the reopening.[^1][^2] | ||

| 17 | The [IMTUG booklet](https://ironmind.com/.galleries/pdfs/IMTUGBooklet-070516.pdf), carrying a 2015 copyright, preserves illustrated hand positions, a model-selection chart and maintenance advice. It cautions against resting the spring against the hand and explains that IMTUG should not be held like a conventional full-hand gripper.[^2] | ||
