Dahle's Lead Pointers are designed to be used on 2mm drafting leads, these sharpeners gently shave the outer edge of the leads and provide a perfectly contoured edge. Each unit features integrated steel milled blades that the pencil rotates around and spins freely once fully sharpened. Dahle Lead Pointers are handheld devices with plastic bodies that catch lead shavings and include a cleaning plug to remove excess lead shavings. The 301 includes an automatic cutting stop mechanism to prevent over-sharpening. This model also features two measuring devices, one for writing and one for precision drawing points.
