If like me you have the fine motor skills of a drunk monkey I have found an idiot proof pocket sized sharpener(IF I CAN USE IT IT MUST BE IDIOT PROOF )It is made by BLADETECH and can be ordered via the internet from the companies website.It is basically two pieces of tungsten carbide mounted in a piece of metal it's simple and effective and can be used on knives ,garden tools and scissors.
There are far better systems out there LANSKY ETC but this is ideal for putting an edge back on a hard worked blade until you get back to your more in depth systems
