What are the different types of engineer's scriber?
There are four basic types of engineer’s scriber:
Pocket Scriber
Machinist’s Scriber
Doubled-ended Scriber
Knife-edge Scriber
Pocket Scriber
These are small scribers about 100mm (4″) in length. They often feature replaceable tips and a hexagonal head to prevent them from rolling off work surfaces.
Machinist’s Scribers
Machinist’s scribers are just longer versions of pocket scribers, usually 150-200mm (6-8″) long. They often have a clip similar to a pin to secure them onto jacket pockets and prevent them from rolling off work surfaces.
Double-Ended Scribers
These scribers feature a straight point at one end of the scriber and can have a variety of angled points at the other.
The angled point allows lines to be marked on the workpiece in confined areas such as inside holes or on the underside of ridges.
Knife Edge Scriber
Knife edge scribers have a straight point at one end and a flat knife blade at the other and can range in length from 100-250mm (4-10″). The knife blade is used for marking lines on wood, plastic and other soft material.
They have several other names including ‘striking knives’, ‘scoring knives’, ‘layout knives’ and ‘marking knives’, although most of these will only feature the knife blade and not have a scriber point at the other end.
