The blades in Gerber knives and multi-tools are engineered from high quality stainless steel that excels at edge retention. Still there comes a time when proper sharpening is called for. For those occasions, we offer an extensive array of sharpening solutions. We're talking about everything from diamond to stone to ceramic to steel. The solution you choose depends on what you're sharpening, and which method you prefer. Whatever the case, Gerber's got you covered.
I have attempted to sharpen two knives, one a $9.95 special and the other a $100.00 investment. So far I'm unimpressed with the outcome. It was not an expensive sharpener so I'm not out but a little time.
