Traditional Upholstery Knife for Cutting Foam Sheets, Cushions & Block Foam
The Manual Foam Cutting Knife is a classic upholsterer’s tool designed for clean, controlled cutting of upholstery foam, foam sheets, block foam, cushion foam and mattress foam.
With its long 12-inch straight steel blade and comfortable beechwood handle, this knife allows you to cut foam by hand with better control than a general-purpose knife. It is ideal for trimming foam to size, shaping cushion interiors and making straight cuts through many common upholstery foam grades.
This is a proper, traditional workshop tool — simple, reliable and built for the job. No fuss, no gimmicks, just a good sharp blade and a steady hand.
Why Use a Manual Foam Cutting Knife?
A standard household knife or small craft blade can drag, snag or tear foam, leaving rough edges and uneven cuts. A proper foam cutting knife gives you a longer cutting stroke, helping create smoother lines and cleaner edges.
It is especially useful when preparing seat cushions, back cushions, arm pads, foam inserts, mattress foam and upholstery replacement pads.
For thicker or more detailed cutting, powered foam cutters may be quicker, but for general trimming and hand-cutting work, a manual foam knife remains one of the most useful tools in the upholstery trade.

Foam Cutting Tips
For best results, use long, steady strokes rather than short sawing movements. Let the blade travel through the foam smoothly instead of forcing it.
Keep the blade sharp and clean. A blunt blade will pull at the foam and make the cut untidy — and nobody wants a cushion edge that looks like it lost a fight with a cheese grater.
For straighter cuts, mark your cutting line clearly first and work on a flat, stable surface.
