I performed some testing in regards to Throwing Ham. Here are some rules to the Ham Grind:

1: You need to wait for the Throwing Ham to teleport to you before crossing the screen. It will not duplicate if you just throw and cross immediately.

1a: You need to grab the original Throwing Ham after the duplicated Throwing Ham drops.

2: The location is irrelevant and can be duplicated almost anywhere (I say almost, because there might be some Unity Programming magic somewhere. This was done at the Goblin Camp because it's where I found out about this Glitch)

3: Do not stand too close to the edge of the screen transition. The ham might bounce back into the code void.

4: If you throw multiple throwing hams at opponents, and they have not teleported back, the first teleportation will combine them all as one Throwing Ham. HOWEVER, if you throw one Throwing Ham, and it teleports back to you, you are free to continuously throw them to your heart's content without risking them teleporting back to you. This is not based off of distance, and I used the Goblin Camps as a reference.

4a: HOWEVER, if one of those Throwing Hams gets thrown past the transition screen it will set off the parameters for teleporting the Throwing Hams and they WILL overlap the sounds of all the Throwing Hams at the same time.

5: Throwing Hams cost 30 Gold.

Note: I do not know how prevalent this information is. I did not see anyone talk about it (on steam) so I thought people should know so we can cheese this game together.
