I have just got a new decent knife and want to know the best way to keep it nice and sharp the knife in question is a Gerber gator
i have seen ceramic rods, water stones oil stones diamond stones and the ubiquitous bench grinder (which i take is out as it heats the metal reducing its temper but how/ what do you use? i have also seen a sharpener in tescos for kitchen knives which has a handle and a spring loaded v shaped hole you draw the knife through. but what works best with the least chance of an knife blade ruining incident and getting the best sharp edge right to the tip? been stainless is it hard to sharpen?
