Umm,, I'm a knife guy,, bla bla bla.
In the past, I have tried to pass along info about how to sharpen a knife, how to use a "Water Stone" and how to find your edge's angle.
It is this last topic on which I want to share additional info.
*if you read my posts at all*, I told you how I usually find my edge angle by stroking the knife forward on a stone and slowly raising the knife's angle until it just begins to "bite" into the stone. Then, backing off just a bit to get the angle right.
Well, there is a different way to find that angle.

Take a "Sharpie" or some such "Permanent Marker" and mark the entire edge from the tip all the way down. Cover the entire edge.
*not the entire blade,, just the edge*
(
remember, the edge is the part that runs along the entire length of the blade and is the part that forms a "V"
on the sharpest part of the knife. Look close. This is the part that you are trying to sharpen.)
Now, if you can find an angle on your sharpening tool that scrapes off
ALL of that sharpie mark at the same time, you have found your angle.

Good luck.
Ps: This only really works on a "Flat" edge (most come from the factory with a Flat edge)
you can guess from the diagram what happens to any other edge type.
