Query: I love AccuSharp!

We have both the knife and scissor sharpeners. I have had every type of sharpener from a manual Henkle's unit to the top of the line Chef's electric sharpener and these little babies out-do all of them. Simple operation and very inexpensive. If I was only able to sharpen all my scissors and knives only once before having to replace the AccuSharp it would be worth it but so far these have held up for months. Am looking forward to picking up the lawnmower and garden tool unit next.
