Abstract: An accessory is provided for a conventional workshop table saw that allows the table saw to be utilized to sharpen the blades of knives. The accessory includes a channel follower adapted for engagement in a guide channel formed on the flat planar surface of the table saw. A knife cradle is connected to the channel follower and is selectively movable in a transverse direction to adjust the spacing of the knife cradle from both the guide channel and a rotary blade element slot defined in the planar work piece table top. A grinding disk is mounted as a rotary blade element in the table saw and a knife, positioned in the knife cradle, is advanced past the grinding disk to hone the knife blade.
