No problem guys. After all the help I've gotten from this board it's the least I could do.
As far as why does it have Two angle adjustments Dave, I believe it's used when you have a really big pair of Grass shears or scissors. Remember this device can be used for more than knives with the optional wedge. It also does chisels, plane blades and tin snips to name a few others. Your not "LOCKED" into just a few angles. Because of this double adjustment the angle you can get is basically infinite.
I really don't see a down side to this unit for a novice or a professional if used in the right capacity. Now I have to get me some Shapton Glass stones and some extra sandpaper.
