Advantages of Single Bevel blade?

[geohans]

I searched and got hundreds of threads with these two words, but did not come across an explanation of what advantages there might be for a truly single bevel blade-- which I understand to be one side with a bevel, the other completely flat.

Please let me know what advantages there might be, including in the manufacturing process (which I suppose is obvious), but also the disadvantages.

Thanks!

You mean a chisel grind blade?

They are easier to sharpen. They are aesthetically pleasing to some.

On a thin knife (like a chef's or sushi knife) many claim they increase fine slicing ability. On thicker blades I see no real advantage at all, and in fact quite a few disadvantages.

It is sharper typically, unless someone specifically makes the edge too obtuse on purpose, you have half the edge. BTW, not that easy to use, takes time to learn.

I think they look cool, are nice to slice with, and are really easy to sharpen.

Precisely. It always helps to search using the right terms! :thumbup: Seems to be a bit of that going around lately.

To me, they are of no particular advantage unless you are slicing sushi, and their "handedness" is a disadvatange.

The advantage lies entirely on one factor and that's the dynamic of edge angle per side vs. lowest angle of possible approach. If you have a conventional knife with a 30° edge (15° per side) then the lowest angle you can approach the cut from is 15°< or anything greater than 15°. At 15° your edge bevel will run parallel with the target and will not bite in. With a knife that has matched edge angles per side, you have an equal approach limit on each side. With a single bevel knife with a 30° edge (0° on one side, 30° on the other) you can approach the target at any angle short of lying the blade flat against it and it will cut, while the opposite side will not cut at any approach 30° or shallower. The absence of a secondary bevel on the flat face will make paring cuts difficult since there is no fulcrum to lever out of the cut with. However, on chopping tools a chisel grind completely eliminates any chance of glancing blows on the flat face, since glancing blows arise from approaching the cut at an angle more shallow than the edge angle.
