3pcs Replacement Blades for Scribing Tool Thingamejig,9110002

After continued use of your scribing tool, the blades will need to be changed. Accuracy cannot be guaranteed if non-genuine blades are used. The scribing tool has 9 blade tips, of which 3 are always exposed, so you can quickly change to another tip if one goes blunt. This prevents downtime due to blade changes. As required, simply undo the wrench screw holding the blade and rotate to an unused sharp point on each triangle blade. Remember not to over-tighten.
