MonumenTOOLS - Hobby Nerd Cutting Mat

The Mold Line / Seam Scraper gives you a high quality, stainless steel blade for taking down unwanted seams along the perimeter of your model and mold imperfections. It provides two blades, each with an opposing angle to get into tight spots from any direction. The curve of the blades allows for minimal surface contact, so that you don't have unwanted tool marks on the surface of the model. Simply scrape the blade along the surface and watch those seams disappear.

Great for resin, plastic, and even metal models.
