1pc Circle & Arc Cutting Template Board, Double-Sided Black Cutting Mat with Concentric Circles, Radius Arcs R300-R750 and Polar Grid, Hobby Knife Cutting (3853)

Listing Description (181.4*99.7*0.2MM)

• One Board, Every Curve: front face combines concentric circle targets with center crosshairs, large-radius arcs from R300 to R750, and a full polar coordinate grid — circles, arcs and radial layouts are all cut or scribed from one board.

• Cut or Scribe, Your Choice: works as a cutting template for panel lines and round hatches, or as a scribing guide for recessed detail — the smooth black face lets the knife glide without snagging.

• Polar Grid for Radial Work: the large ray-and-ring grid handles fan-pattern panel lines, wheel spokes, radar dishes, round windows and any layout drawn from a center point.

• Double-Sided Design: printed front for template work, plain black back for general cutting — flip it over and it doubles as an everyday cutting mat.

• Modeling & Craft Ready: ideal for sci-fi round hatches, aircraft panel arcs, ship portholes, architectural plans, leather and paper crafts. (Knife and models shown are NOT included.)
