A nice, useful piece of kit. The sharpening setting is quite fine, so while it will put a nice (very nice) edge on a slender blade, don't try it on anything too beefy. The diamond spike, on the other hand, is VERY course. Use lightly. The whistle and spark-striker are a little under-whelming but quite functional for all of that.
Overall, well worth the price for an emergency back-up.
