No wonder my VG-10 Spyder bites heal so well...

You aren't calling me fruit-like are you?

I have a Wegner grafting knife and its steel is not nearly as 'surgical' as VG-10. My Wegner is a very good knife for a fruitman but in VG-10 it would be better.

You sure could do emergency surgery with my VG-10 blade...

I always thought surgical steel was the same as stainless, just it has extra protection against sharding.

Ed I can understand why the aus-grain would be finer due to the vanadium, however it seems to be the carbide size would be far too large if the goal was to have maximum sharpness for minimal tissue disruption and Cold Steels VG-1 would be superior for that purpose. I would however be interested in any test data on VG-10, especially a picture of the microstructure.

In general, there are a number of high quality steels designed for razor blades, AEB-L/13C26 is such a steel. That is a stainless steel designed to have a small volume, <5% of very small carbides, < 1 micron. It is the stainless steel which current has the highest ability to take and hold a high polish at acute angles. The sharpest surgical instruments are made from diamonds and they have an edge much sharper than steels, they are about 10 atoms thick.

Iirc scalpels actually rust pretty easily. Of course they would, being really hard and brittle, and not expensive due to being disposable.

Ahhh...enlightenment! :D
