The square or useful hand is found everywhere and people with this shape are conventional, rather set in their ways, and have great respect for law and order. They are very practical and pragmatic. Orderly, logical, and methodical, they have an endless patience, are level-headed, but can also be determined and even stubborn when they choose. The square hand implies a precise, methodical, and practical nature, so this type of hand with many palm lines indicates a sensitive and artistic character, impressionable and, perhaps, with an excess of nervous energy. So it is best for there to be only a few lines on this hand, because if covered with lines, the person concerned can be confused easily. A square hand with few lines indicate a practical and down-to-earth approach.

Conic or Round Hand 
Conic is a very old term for round. When the hand and fingers are conic, there is a slight tapering to the fingertips. The edges of the hand seem soft when compared with a square hand. In this type of hand the outer edge of the palm has a definite curve

This hand shape indicates a creative and artistic nature, along with an impulse and idealistic side. These people like change, and will make and break relationships, not because they lack feeling, but because they just like the stimulus of the new and untried. They have a very low boredom threshold and they will try anything once – twice if they like it. On the conic hand, which indicates sensitivity, we would expect to find many palm lines, because it is in the nature of the person to be constantly prepared for variety and the stimulus to change. A few lines here suggest the more self-reliant type with a sound constitution and a good balance between nervous energy and physical activity.
