Can you sharpen a convex edge on a stone?

Sharpening on sharpening stones is the most popular way to sharpen knives yourself. You can easily sharpen a convex edge with a sharpening stone. Place the blade on the sharpening stone to make sure the edge is not resting on the stone.

What angle is a convex grind?

The working angle of sharpening is usually 36°, sharpening is performed with a gradual increase in the angle. TSPROF device for the convex edge sharpening allows you to effectively sharpen knives into the lens both with bevels from the spine, and with a concave lens, and even with “Scandi”-bevels.

Is a convex edge better?

A convex edge is slightly rounded (hence the name convex) as it tapers off to the finest point of the cutting edge along the blade. The convex edge is considered superior compared to other edge grind types due to longer lasting durability and less drag when cutting.

What is a Scandi grind?

What is a scandi grind? A scandi grind is basically one of the easiest way of turning a piece of steel into a knife. A flat piece of 2-3 mm thick steel only has one slight curve towards the edge. That’s it. Not another secondary edge as you often find in kitchen knives, for instance.

What makes an edge sharp?

First, it is good to remember that a blade is sharp because its thin edge has numerous serrations at a microscopic level. ‘ A little at a time, the serrations completely disappear and the blade is no longer able to cut the material. After all, a blade is a type of micro-saw. This is the time when it must be sharpened.

How do I find the sharpening angle?

The sharpening angle for your knife is half the angle of the cutting edge (after all, you will sharpen on 2 sides). The sharpening angle of a Japanese knife (please find a few examples below) is therefore 15 ° (30 °/2) and of other knives 18 ° to 20 °.

What is a Granton edge?

How to maintain the edge of a convex knife?

To maintain the edge on a knife that already has a convex edge, all you really need to do is to use a marker and find out what the final edge angle is. There are detailed instructions of finding your angle here: Finding Your Angle.

What is the advantage of a convex grind?

With a convex grind you sharpen the entire curve of the blade and not just the edge / the cutting surface. If the curve runs over the entire blade (up to the spine), it is even easier to sharpen. You namely don’t have to stop sharpening halfway through the blade.
