I am looking for a commercial source of cauterizing synthetic diamond double-lancets

There was a publication suggesting these are available:
Link2

But I have only found a single supplier of regular blades:
Link2

This intended use was for industrial purposes, and does not need to be medical grade.


Does anyone know of a sub-$200 source?


Specifically, I am seeking a description of the wear life compared to heated stainless steel.

I did a Google for you, but the item you link to seems to be an idea rather than a product. Diamond is a superb thermal conductor (much better than copper) so it should be very easy to heat any diamond blade held in a metal clamp/handle by simply heating the clamp/handle. Can't help beyond that. I've always wanted a diamond scalpel, but I wonder if in practice it's edge is very brittle making it only suitable for soft materials, like ceramic knives.

Diamond blades can cut metals and ceramics but the force and angle must be perfectly controlled. I doubt many people on earth can do it by hand.

The lifetime would probably range from forever to a second depending on what is being cut and how.

FYI:
Based on the tooling wear life,
I looked into a lower cost plasma sharpened Diamaze product.

Wow! Those are very interesting!

Any guesses how Plasma Sharpening works?

Nice pics Link2
