GENTLE ON YOUR BLADES: Our knife guards are felt-lined so that they protect your knives’ integrity without marring their finish or dulling their blades as they slide in and out of the sheath. | SAFER, NON-BPA MATERIALS: Our chef knife covers are constructed from ABS plastic, which unlike its common alternative PVC plastic, is non-BPA and non-toxic. | LONG-LASTING CONSTRUCTION: In addition to it being safer, we chose ABS plastic over PVC for our knife sleeves as it is harder, more resistant to abrasions, and has a higher impact strength. We also designed our knife sleeves to be thick, cut-proof, and more durable than thinner, flimsier edge guards. | UNIVERSAL KNIFE BLADE SIZES: 5-Piece assorted knife protectors are designed to fit most paring, utility, boning, Santoku, chef, and bread knives. See dimensions below to determine if your specific knife set is well suited! | KNIFE SHEATH DIMENSIONS: (1) 4.75" x 1", (1) 6” X 1”, (1) 6.25” X 1.25”, (1) 8.5” X 2”, (1) 10.5” x 2.25”.
