Listings commonly show foam cutters designed for foam and related craft boards, including foam board and KT board, EPS/Styrofoam, pearl cotton, EVA, XPS, PE (polyethylene), sponge and rubber.
Electric foam cutters span a wide power range in these listings — from lower-power kits around 18W, through mid-range carving knives near 120W, up to higher-power hot-knife tools around 200W.
Hot cutting tools are described as delivering smooth, clean and precise cuts that often seal edges and leave little or no debris, making them suitable for intricate shaping and detailed work.
Search results show both electrically powered hot knives and manual hobby/utility knives. Several entries list electric power supplies for hot-knife tools, while some hobby/detail knives are manual (no battery).
Higher-power hot knives list wide, stepless temperature ranges (example given: about 122–932°F). Smaller kit-style cutters report faster startup — for example, reaching roughly 150°C in about 10–15 seconds for quick use.
Kits commonly bundle extra blades plus basic tools and storage: examples include cleaning brushes, a wrench and a tool case. Larger kits may add holders, replacement wire, transformer adapters and digital voltage controllers.
