I haven't seen any posts claiming dissatisfaction with any of the sharpening pastes. Most prefer a water based as against an oil based paste for allergic reactions, but I often mix neatsfoot oil with my water based paste on a piece of leather with no problems, as I wash the blade after sharpening with paste anyway. Lynn has had good results with TI paste, I have had good results with Amplex paste. I don't know what brand handamerican offers or if it is their own private label. Everyone seems to love handamerican products and service though.
