The Compo Knife Composite Instrument is a precision dental tool engineered for the placement, shaping, and contouring of composite restorative materials. Designed with the practicing clinician in mind, this instrument combines ergonomic balance with functional blade geometry to support accurate, efficient restorative workflows.
This instrument is well suited for incrementally placing and adapting composite resin in Class I through Class V restorations. Its blade profile supports precise marginal adaptation and interproximal contouring, helping clinicians achieve anatomically accurate results with minimal finishing time. The instrument integrates smoothly into standard direct bonding protocols and is compatible with all major light-cured and dual-cured composite systems.
The Compo Knife Composite Instrument is fully autoclavable and compatible with standard sterilization pouches and cassette systems. Routine inspection of the working tips after each sterilization cycle is recommended to maintain optimal clinical performance.

Is this instrument suitable for use with flowable composites? Yes, the blade design accommodates both packable and flowable composite materials across a range of viscosities.
How many working ends does the instrument have? The instrument features a dual-ended configuration, offering two distinct working surfaces in one handle.
Can it be used in both anterior and posterior restorations? Yes, the instrument is designed to support a broad range of direct composite restorations in all regions of the mouth.
