With the DF6 Sharpener you get perfect 30 degree edges quickly and easily every time. There are no special skills needed to sharpen all types of knives and axes. The specially curved diamond coated fingers replicate the swipe across a traditional honing steel. One swipe through the DF8 equals six swipes across a regular steel. Once you use this sharpener blades almost never need regrinding because the edges never get rounded like they can with other honing and sharpening steels. Small table top, compact design.
I've used numerous types of sharpeners over the past 40 years. This little thing is amazing. It's my favorite go-to sharpening. I keep one in my kitchen and one in the shop.
One stroke and I"m cutting tomatoes effortlessly. Far better than any ceramic sharpener I've used.
Form follows function in this design. It's not over built, just simple and highly effective.
