When you harden carbon steel in a quench it is actually surface hardening. The core of the part stays soft. Water is used to make the hardest surface as the quickness of the cooling determines how much carbon is brought to the surface. Oil cools a little more slowly and is better for a part that needs to be a little tougher. When you need something to be wear resistant water hardened 1045 is hard to beat. Fairly easy to get Rockwell 60 on the surface. The most exotic hardening steel I have worked with is ASTM 52100 high carbon chromium bearing steel. Water hardens to over 65 Rockwell.

I used these homemade ones Joe made for me yesterday and they seemed to work a lot better then the ones baileys sales us that are so brittle and break easily. 

Heck I heard baileys dont even sale the ones for the breaker set I bought from them anymore    . So this could be a blessing in disguise. 

Thanks for getting me these all away around the world to try out. 

Joe,
This is a great idea.  Thank you for posting the video because that explains it better than ever.
