ok i have done some search here and some folks are get good results with this oil at 100 F. before i shell out the 40 dollars a gallon i want to make sure i am make a smart purchase. First of i mainly use 01 and make my knife very slowly and make them for friends and hunting buddies. I want to take my knifes to the next lvl and i think moving up to a proper oil will help much. Also i have avaliable to me is the John deere load shafts. Since my dad is a parts sales manager for john deere i get all the load shafts that get replaced in the shop. (free i may add). would this oil also work for a forged out blade 5160 or would another oil perform better? i looked at tough quench for it easy to get item unlike some of the other oils. Thanks for any and all thoughts.
