# Best Parts Separators: Open Seams Without Damage Source: https://modelbuildlab.com/best/best-parts-separators Updated: 2026-09-15 Publisher: Model Build Lab. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://modelbuildlab.com/how-we-research#our-score A parts separator is a thin wedge-shaped tool that splits assembled model parts apart without gouging or snapping them. Scale modelers reach for one when a Gunpla snap-fit joint needs to come apart for painting, when a test-fitted assembly must be opened, or when a misaligned glue joint needs correcting before the cement fully cures. Compared to prying with a knife blade, a separator spreads force along the seam and protects both the part and your fingers. When choosing, look at blade thinness and taper, tip width options for different seam sizes, handle grip for controlled twisting, and plastic-safe edges that will not scar visible surfaces. This guide compares the separators worth keeping on your bench. ## Picks ### 1.
