Product Brief

Manufactured from high quality spring steel, Straight & Knife Edges are fully ground and hand scraped for a perfectly flat surface. Hand scraping removes all the high points left from grinding making these an extremely accurate tool

The thickness and design permit these to retain shape & accuracy yet convenient to carry around

Used for drawing & scribing straight lines, checking surfaces for straightness, setting up machines such as planers etc. these are available in two types:

Straight Edges - These have flat edges on both sides

Knife Edges - These are flat on one side and have a bevel on the other that provides an excellent visual line contact with the work piece
