Dr Vadim Kraichuk RIP 2022 He talks about it more in his book on page 54

Next level after that is controlled testing, graphing the data and sharing or keeping for internal QC.

I used to sell them on my website back in March 2020.

About Laser Goniometers A lot of folks here would probably poop themselves if they saw what angles they are ACTUALLY creating rather what they are imagining. A lot of 10dps chest beating, machismo is going to evaporate when guys see some laser reflection patterns on that "10dps" showing...

CPM 20CV, can see the ~2-4μm carbides at the edge

Freehand produces convexity, you're never going to get an exact angle with that method and that's not what is holding you back. Free handing is about consistency and good consistency will naturally blend the angles from the shoulder of the bevel to the apex. (Not blending into the grind) If...

Gunny Juice has been the best I've used so far. CPM 15V at 65rc Each of those dark spots is a carbide at 87rc at 1-2um in size. This was an incredible edge from Gunny Juice. If it could make an edge like this on an extreme material it should be able to eat everything.

King Neo 800 👍

Too fancy for me. Thanks man.

Interesting. I found it was the opposite. The simple carbon steels are more prone to developing plate martensite since the cementite dissolves rapidly past Ac1 easily putting too much carbon solution if a proper time and temperature isn't selected. Meanwhile, in tool steels, the other metallic...

Which one has which?

That was CPM S110V.

Some Color etch metallography I did of CPM 15V. Cream colored vanadium carbides in a blue matrix of tempered martensite. CPM 15V edge at high magnification. Carbides have been exposed from matrix with sharpening technique, this increases aggression. Carbides are ~3um average size. CPM 15V...
