The DelGuard Mechanical Pencil made by Zebra has a double spring mechanism built into the pencil to prevent lead breakage from multiple writing angles.A spring in thebody of the pencil allows the lead to bounce when pushing down, making the lead slide back into the metal sleeve if force is applied straight down (for those who hold their pencil straight when writing); another spring towards the tip of the pencil allows the lead to move back into the sleeve if force is applied from an angle (for those who hold their pencil at an angle to the paper when writing).The DelGuard is a great solution for anyone who tends to grip their writing utensils very hard, write with greater force and often struggles with breaking their pencil leads!
