You can probably get much better advice than me, but I just lay three fingers across the blade and just let the weight of them keep everything in contract (like on piano keys) . I don't put any torque on the stem and just use that hand to push, pull, and steer. So if I'm doing an x stroke, at least two fingers or holding the blade flat on the stone. Warning, obviously you can get your fingers on the wrong side of the edge this way. But that is generally when you are trying to pull the blade with that hand.
I had to look up Moore maker as well. A small company, but based on price, someone thinks they are good blades. I played around with changing the bevel last time to match a similar knife I have.
But I didn't have the time or patience that night.
