Ceramic Honing Rod
As you use any Chef's Knife, the edge will curl over and require "honing". The rate at which this happens depends on a variety of factors such as the cutting surface, hardness of the knife, how hard the cutting surface is struck, etc. While diamond and steel cutting rods do exist, ceramic honing rods are the preferred style for most. They are gentler on the blade of the knife and uncurl the edge without aggressively stripping off material.
These honing rods are 12" of ceramic with a black handle. They feel great in the hand and work wonders on your knife's edge. There are other honing rods to choose from, but this one is our favorite, especially for the Gallatin's high hardness.
Anytime that you feel your knife is less sharp than it should be, its time to get out the honing rod. This can greatly extend the lifetime of your blade and the time between resharpenings.
