microbevel vs secondary bevel

They're the same thing.

One is just much smaller. A microbevel helps temper the force put on a thin edge, take a zero ground scandi grind for example. 9 times out of 10 it will roll without the installation of a micro bevel (unless you are using it on very soft woods).

The terminology seems debatable. This image sums up how I've always referred to the various bevel stages. The primary bevel is the blade grind, whether hollow, flat, scandi, etc. The secondary bevel is the sharpening angle if it is different from the primary bevel. The micro bevel is an additional (generally as small as possible) bevel. I sharpen most of my knives anywhere from 15-17 degrees per side for the secondary bevel, and then use a Sharpmaker to create a 20 degree microbevel between full sharpening sessions.

A bevel is any non-90° angled facet. Some people distinguish between blade bevels and edge bevels. It doesn't really matter how you designate them, as long as you're clear about what you mean.

 

[J. Doyle]

A microbevel is a small secondary bevel. They're the same thing. It's really that simple.

For example, J. Doyle has just indicated that he is referring strictly to edge bevels. Because if he was considering the blade's primary bevel starting at the spine, then he would have called the microbevel a tertiary bevel.

I find that convention of designating bevels a bit more confusing, personally, because every facet on the blade is, strictly speaking, a bevel, so for clarity, if I were referring to the edge bevel as the primary bevel and the microbevel as the secondary bevel, I would call the primary bevel, the primary edge bevel.

can i use the word "differeter" here?

No, sorry, but I wouldn't ever use the word "tertiary" in reference to a knife.

A knife has a main or primary bevel (grind). That either then goes to a zero grind or it has a secondary bevel (cutting edge). If that secondary bevel is very small, it is sometimes called a microbevel.

Let's not overcomplicate a really simple concept.

When someone says primary, secondary etc., it means they are counting the number of something, in this case bevels. It doesn’t make sense to me to call two separate bevels both secondary.

But you think it is less complicated to call both the cutting edge and the microbevel "secondary" even though they are different bevels, go right ahead. I don’t accept the implication it’s the one and only correct way, though.

I think it's less complicated to not add any additional bevel to the cutting edge.

Main bevel. Secondary bevel. Done.

If you're doing more than that, you're overcomplicating knifemaking and this needs to be a different conversation.

Main grind=primary bevel. Cutting edge=secondary bevel. Microbevel=smaller cutting edge=still a secondary bevel.

It doesn't get any simpler than that. Argue semantics with someone else.

I have nothing further to say on the topic.

Don’t tell me, tell the guys who make compound grinds. But if I see one of those knives, I’m not going to say that the first bevel is the first bevel, the second bevel is the second bevel and the third bevel is also the second bevel.

That was fun.
