Crain - Scribing Tool - 18"

This tool accurately scores wide pieces from 2" to 16". It features a two-part knurled brass knob for all necessary adjustments, without a screwdriver. The upper part adjusts the needle height according to the material thickness, and the lower part adjusts the offset distance between the needle and the guide being used. Includes a rounded-end guide for walls and a lower guide for seaming, which runs along the edge of the lower piece of material while the upper piece is scored. The needles are replaceable (no. 371).
