However, it is difficult to sharpen a tactical knife or any knife for that matter, without the right type of sharpening tool. Many of the high-quality tactical knives available in the market are made of stainless steel, a tough material that is hard to hone.

Compared to other materials though, once a stainless steel knife is properly sharpened, it retains its sharp edge for quite some time, even with continuous use. If you’re looking for the best type of sharpener for your knives, go for the one with a rough surface, preferably one that has diamonds on the surface, with the sharpener’s end made of ceramic abrasive or hard stone. This is because these two materials are tougher than steel and will easily sharpen the knife. A stone sharpener is another ideal material to use, although it will require more effort as its hardness is only a bit higher than steel.

Water whetstones need to be soaked in water before they can be used. They are made with softer natural stone or synthetic materials that will wear out in time. This type comes with coarse and fine grits on each side. More expensive is the ceramic whetstone, which has a much harder surface, in two grits and steel that’s coated with diamond bits.
