Works really well for the most part - Lansky 5-Stone Professional System

Ok so I use this set constantly for everything from my dads camping knife to my moms kitchen knifes and it works really well for that. the setting are accurate and have a nice range for edge angles (i guess that's what they're called?). however I must admit that when you used it on the 17 degree setting the bar and actual stone end up running into the red tensioning knob which makes it a bit of a pain to sharpen that section of the blade without turning it over which is the only reason it gets 4 out of 5 stars. I even tend to take this with me when I go camping or hiking since it is relatively light and self contained.
