Think of it as a Sharpmaker for your pocket. Two small pairs of ceramic rods in a compact plastic holder.
I got my Gatco in a Sentry Solutions Kit that came with the Gatco, a tube of Tuff Glide lubricant/protectant and a couple other little things for under $30.00. The Gatco and the Tuff Glide alone were worth the price, but I think the Gatco alone can be had for under $15.00.
The other option would be one of the DMT Duo-Fold diamond sharpeners. It would probably set you back a few dollars more, but would be more useful for a real sharpening job, where the Gatco Micro X is more suited to touch up work, although it could probably do a major re-sharpening if plenty of patience was applied liberally.
