In the earliest episodes, the scythe had a brown handle, was somewhat bent, and had a knob on it. In the rest of the series, it has a smooth, strait black handle.
All the most prominent of Grim's powers stem from this scythe. For the most point, Grim is dependent upon the scythe in the series for his powers and is usually rendered powerless when disarmed, but has been seen shown as capable of magical feats without it.
The Reaper's Scythe has the ability to cut and slice through anything and, according to Jack O'Lantern in Billy and Mandy's Jacked Up Halloween,anything that has been cut by the scythe's blade cannot ever be repaired; however, when Billy cut off Grim's head with the scythe in The Incredible Shrinking Mandy Grim put his head back on. This may suggest that the wielder must intend for the object to stay off in order for it to work.
The Reaper's Scythe can be used to open rifts to 'the other side' it's main purpose being to open the way for the souls of the recently deceased to pass through.
The scythe, however, is not limited to just cutting through obstacles and opening portals, as Grim has also used it to open inter-and-extra-dimentional portals and rifts in the fabric of time and space, and cast spells. The scythe's blade can be used to fire bolts of energy at targets, give off light, deflect incoming energy blasts and put up protective barriers (Which Came First?,) and the handle can be used like a Light-saber, (Brown Evil).
In Hurter Monkey, it was shown that the Scythe is able to hold Grim to his promise to be Billy and Mandy's best friend, preventing Grim from leaving Mandy's house with the intention of never coming back. In Billy Idiot, Grim admits that the only way a evil witch can overpower his scythe is if she can first turn it into a snake, and then turns it against him. In The Grim Adventures of the Kids Next Door it is shown that Grim could feel that the scythe had become fused with a bunch of children who were evil, but oddly delightful.
