Milwaukee Grease Gun Redesign
Grease guns are often a messy, unappealing tool. Even with the most premium of grease guns, they are consistently messy products that get grease everywhere if loaded or used incorrectly. And, even in the case they are used correctly, they can be a messy product nonetheless.
Issues to Address
The process of loading a grease gun in itself is also unpleasant, there are many steps, and often the recomended method by the manufacturer isn’t even the one preferred by users.
In addition, the grease guns can be a pain to carry and lock onto grease fittings.

Always a Mess
Since it is a tool used to pump grease
2
Difficult Reload
The grease gun is unpleasant to reload. The empty space found in the cardboard grease tubes means a lot of priming, and there are many places where the grease can seep out. Even if primed correctly, grease will seep out a designated area with noting to catch or contain it.

No Free Hand
Since most users just hold the nozzle up to the grease fitting, there is little reason the grease gun has to be two handed, other than the trigger is on main body of the tube. A different trigger location may make it easier to carry as a satchel, (which is an option the Milwaukee grease gun already has).
