Input:
I have been sharpening knives for over 45 years and this is the fastest, easiest way to get an excellent multi-angle edge on ALL of your knives. I orginally purchased a Model 300 about 12 years ago. The 310 is much better because it sharpens all of the way to the handle, a big issue with small blade pocket knives.
If you like sharp knives and either do not have the skill or the time to do it by hand get yourself one of these.
