GRS 022-470 #0 QC HSS Knife Graver – 1.8 mm
The GRS 022-470 #0 QC HSS Knife Graver is a precision 1.8 mm Quick Change (QC) knife graver designed for fine engraving, deep narrow cuts, inlay work, detail engraving, and precise material removal.
The Knife Graver profile features straight sides that angle inward toward a small, sharp cutting point. This geometry produces a narrow, concentrated cutting edge that is especially useful when a precise, deep cut is required.
Made from high-speed chrome tool steel, the 022-470 is engineered for durability and dependable edge performance in professional engraving and stone-setting applications. The factory-shaped tip and ground QC shank help reduce initial tool preparation and allow the graver to be quickly installed in a compatible GRS Quick Change holder.
At 1.8 mm, the #0 Knife Graver is the smallest size in the GRS QC Knife series, making it a strong choice when you need a relatively narrow knife profile while retaining the ability to make deep, controlled cuts.

Precision Knife Graver Profile
A Knife Graver has straight sides that angle inward toward a small, sharp point. This creates a narrow cutting geometry that concentrates the cutting action into a precise area.
Unlike broader flat or round gravers, the knife profile is particularly useful when the engraver needs to reach into a narrow area or make a deeper cut without removing excessive material from the surrounding surface.
GRS recommends the Knife profile for fine engraving, removing excess material in small areas, undercutting inlays, adding detail, and applications requiring deep, narrow cuts.
Fine Engraving & Detail Work
The 022-470 is an excellent choice for fine engraving and detail work where a narrow, concentrated cutting edge is beneficial.
The sharp point allows the engraver to establish precise cuts and work into smaller areas of an engraving design. It can be especially useful when adding details that require more penetration than a broader graver can provide.
Deep, Narrow Cuts
One of the primary advantages of a Knife Graver is its ability to make deep, narrow cuts.
The narrow cutting profile allows the tool to penetrate into confined areas while maintaining a relatively small cutting footprint. This makes the 022-470 useful for detailed metal removal and applications where access is limited.
Inlay Undercutting
The 022-470 is particularly useful for undercutting inlays. Its pointed profile can be used to remove material in small areas and create the controlled undercuts needed for certain inlay techniques.
The 1.8 mm size provides a relatively narrow option for detailed inlay preparation and precision metal removal.
Detail & Material Removal
The Knife Graver is also useful for removing excess material in small areas and adding detail to an engraving.
Its sharp point allows the engraver to target specific areas rather than removing a broad section of material. This makes it useful for refining designs after the primary engraving cuts have been established.
High-Speed Chrome Tool Steel
The 022-470 is precision made from high-speed chrome tool steel, providing the hardness and durability required for professional engraving.
GRS uses high-speed chrome tool steel for its QC Knife gravers to provide reliable cutting performance and edge retention when properly sharpened and maintained.
Factory-Shaped Tip & Quick Change Shank
The 022-470 is supplied with a factory-shaped tip and ground Quick Change shank. This saves time compared with starting from a completely unshaped graver blank.
The QC shank is designed for use with compatible GRS Quick Change holders, allowing the engraver to change tools efficiently during a project.
QC Holder Compatibility
The GRS 022-470 is designed for use with the GRS Traditional QC Tool Holder #004-803.
The Quick Change system makes it easy to switch between different graver profiles and sizes while working, which is especially useful when a project requires several engraving tools.

Straight-Line Control
Because of its narrow, pointed geometry, the Knife Graver is generally easier to control for straight cuts than curved cuts. GRS notes that this profile is preferred for straight lines and can be more difficult to control when cutting curves.
For curved engraving, an onglette or another appropriate graver profile may provide better control depending on the application.
