 Post subject: How to Find Proper Sharpening Angle

Hi All,

I have been sharpening my own knives for about a year now. I'm no expert at all, but I am alright at getting a sharp edge.

For my current knives, I've known the correct sharpening angles (sharpening angle from shop/factory) through the manufacturers or product reviews. For example, I know my Shun is a 50/50 edge at 16 degrees. When I sharpen I don't get too picky about a keeping an exact angle as long as my sharpening stroke is not wobbly and consistent.

I have two knives that I will be sharpening for the first time in the near future and I've no idea what the angles are - the Tojiro DP 210 Gyuto and the Masakage Yuki 240 Gyuto. I'm not obsessed with necessarily maintaining these factory angles, but I would like to know what they are. Any ideas on how to find out this info?

Use the sharpie trick to find the angle. Should be around 15*.

If God wanted me to be a vegetarian he wouldn't make animals taste so good.

+1 to the Sharpie Trick......paint the edge with a Sharpie, and make a few passes on a dry stone adjusting the angle until you're removing the Sharpie across the entire bevel.

And please do keep in mind that the factory bevel angle on most knives can be safely lowered. I typically lower them a bit each sharpening until they fail and then go back up a touch.

Numbers are only a suggestion. Just carefully keep the angles as consistent a possible. Raise a burr on one side, sharpen other side and hope that both edges meet without creating a pronounced wire edge. It's nearly impossible to eliminate burr in it's entirety but if you do a good job keeping consistency the edge will be good.

Just because you can sharpen at steeper angle doesn't necessarily mean it's better. Suppose you happen to sharpen at a less steep angle but do a very good at keeping the angles consistent. I don't think you are going to complain about the performance :)
