Thread: Calculating the Bevel Angle

My goal is 3.5:1 ratio blade width/spine thickness. I like the greater angle since it results in a smaller bevel width which makes it easier to hone.



3/16"..............5/8"................8.63 degrees...... ratio 3.33
1/4"...............5/8"................11.54 degrees .....ratio 2.5
3/16"..............3/4"................7.2 degrees ........ratio 4.0
1/4"................3/4"...............9.6 degrees .........ratio 3.0
3/16"...............7/8"..............6.2 degrees .........ratio 4.6
1/4"...............7/8"................8.2 degrees .........ratio 3.5
3/16"...............1".................5.4 degrees .........ratio 5.3
1/4"...............1"..................7.2 degrees ..........ratio 4.0

Just my $.02,

I see, the numbers I used to calc were all just hypothetical to get an idea of the effect of varying the blade width and spine thickness. If you multiplied the angles by 2 to get the full angle of the edge it looks as though it is about 16 degrees at a ratio of 3.5:1.
