The best resharpenable carpet knife features a long 3" blade with greater thickness for rigidity and durability. The gentle hook of the blade forms a sharp point at the end that does the cutting. After sharpening, the superior German steel alloy holds its edge long after others would be dulled. The wood handle is contoured for comfortable grip, and is riveted solidly to the blade. Net weight: 4 oz. Can be used on all types of flooring. It also features the specially shaped positive grip handle like the No. 102 Knife.
