Description of the issue:

When holding a Steel tool of any kind, it displays as a normal item on the player model, instead of held by its handle.

In first-person, the problem only happens when held in the off-hand. Normal hotbar selection looks correct.

They're using the item/generated parent, but they should be using item/handheld which has the correct orientations.
