If you use a Credo corn cutter, these replacement blades are exactly what you need to keep it working effectively. Made in Solingen, Germany - which is basically the knife-making capital of the world - so you know the quality and sharpness are top-notch. Each pack comes with 6 super sharp blades that easily glide over corns and calluses to gently remove dead skin. They also include a snap-on rasp attachment that's perfect for smoothing rough skin after using the blade. Important safety note though - these blades are seriously sharp, so you need to handle them carefully and avoid cutting live skin. The planer design reduces corns and calluses by gently exfoliating the surface, but you should always use light pressure and go slowly. Perfect for maintaining foot health between pedicures or as part of your regular foot care routine. The blades fit standard Credo corn cutters and are easy to replace when your current blade gets dull. Whether you're dealing with stubborn corns, calluses, or just general rough skin on your feet, these replacement blades help keep your Credo cutter performing like new. Just remember - sharp tools require careful handling, so take your time and be gentle when using them!
