Electric Carving or Bread Knife (East York)

Hello Fellow Recyclers,

Hoping that someone might have an electric carving knife, bread knife or foam cutter they can gift to me.

Need to cut through upholstery foam, 5 inches thick to make a mattress from old couch cushions.

For my personal use only, not for resale.

Thanking you in advance for your time.

Sincerely,
Julie
