TT,
I understand how to use the tip as a chisel even if it doesn't have a chisel grind. That's not at issue.
The geometry of a chisel "tip" with a double bevel "edge" perpendicular to it requires a step between the two to allow them to meet in anything other than an abrupt offset.
That's how Ethan and Ray dealt with it years ago with their bigger knives. The intermediate "step" between the chisel tip and the double bevel edge.
The Razels have no need to do this since they are not a true chisel grind on the tip.

hso, ahhh, a chisel is not to be confused with a chisel grind.
But consider this. If you continued to grind further back on one of the front planes which goes onto to become the double bevel, you would in fact have a chisel and straight grind lines--no step.

Motorcycles, scooters, when will you people realise that automobiles are the best way to get around.

Chico, can't "see" it. All I see is that by creating a chisel ground tip by grinding the side away to meet the front edge on a Razel you end up with a chisel ground knife edge also. You essentially grind away the other bevel. I "see" a wire frame drawing in my mind's eye and every attempt I make to change it to a chisel ground tip with a double bevel knife edge requires that step between the edge and tip. Such are the limitations of the internet forum in the absence of cad drawings.

I was envisioning the knife is the sense that it is now. That is, the belly bevel is left as it is on a traditional knife.
Then Josh picks a side, and grinds on that plane until he creates a chisel profile simply by meeting the obverse side.
Now, having said that, I see no advantage. With a few minutes and a bit of paste, I can take the existing front chisel and give it a mirror finish.
However, the original design is to create a chisel and a razor, not a razor and a perpendicular razor.
A wood chisel should probably be razor sharp. But after seeing the clients who buy Josh's products and the uses, I have to believe that the design is meant to slice, and then scrape and pry.

The answer is in the question. *yep*
<Dr. Pepper, Popcorn, Marlboro Red, Zippo - I ready!>
The nth degree, is the nth degree, and while one chases this degree, they will never attain it, as humans simply cannot grasp the concept. If in theory they did, they would not know how to carry on with "life" as we humans define "life".
The reality is, everything has been discovered, just humans re-discover it.
The answer is in the question.
Why does a hand engraver not put a polished edge on a graver?
How come a butcher can break down more boxes in the freezer area than in the room temperature area with the same knife?
Why does a seasoned fisherman get more fish cut in the North Atlantic than he /she does in a Tropical setting?
How come the sharpest shave a barber gives, is that first shave, from a razor, that sat over the Sunday and Monday he was closed and that razor sat in a glass box with a Tuberculosis light, [UV] and he did not strop it before shaving with it ?
Diamonds have the greatest refraction of light of any gemstone, how are they cut and polished?
Which type of cut presents the best refraction of light and allows the diamond to give off what it does - to the best of "human" ability now.
Why does a scalpel stay sharper in a Operation Room Theatre, than if used in room temperature?
Hint: There ain't no nth, there are degrees for tools for tasks that work best .
Hint II.
Find a old seasoned hand engraver, and look at his/her gravers, sharpened by hand. Look at a 44 Flat, and ask yourself if it does not remind one of a Razel.
Do not look at the 44 Flat sharpened using a Doo-Dad.
The key is in the 44 Flat sharpened by hand.
