Thread: wider bevel=more flex?

So true.

I have been thinking we kinda agree from the start, only use different words for different terms.

Let's rule out the spine thickness. In my first point (that states that bevel planes grow wider with diminishing bevel angle), the grind must be constant, but the spine must vary.
In my second point (the one we seemingly disagree upon) I start from a constant spine thickness.

So, with constant spine thickness, let's assume we are going to cut a strip of 5 mm of two razors, parallel to the very edge. Hence the strip will hold the edge and then some.
Now let's compare those strips:
The first strip comes from a wedge. The bevel sides will occupy a big part of our strip, if not all the strip.

The second strip comes from a full hollow. The bevel sides will occupy only a narrow part of out strip.

The bevel angle on both strips would be equal. But the bevel can't run as far down on the second strip, because their is no steal where it can run into. That steel was ground away by the person that made the razor.

Yep. 100% with you there. It was the "height" thing that I don't think should have been there.

In this case the wider bevel will be a bit sturdier, because it contains more steel for the same height. (it has a wider base).

See, I read that as "height of the bevel". Now I'm thinking you meant height of the bevel for the wedge case and at that same height (which would extend above the bevel in the hollow case). I was pretty sure I understood what you were saying but like I said, I thought maybe you didn't type it quite right?

Well yes, we speak a form of local Dutch back home in Belgium, but most Dutch members wouldn't understand half of it.
So excuse my poor English. I use many expensive words to make it sound intelligent, but the truth is that it is sometimes very hard to express my thought with any precision.
I clearly meant an imaginary strip of steel of equal width on both razors, when I wrote "same height". It's not the first time someone needs to step in and clarify my thoughts...
Thanks for that,

Bart.
