Gauntlets of the Skilled Maneuver.
The feat Hamatula Strike is very interesting, as it allows you to use a successful piercing weapon attack to initiate a grapple. If successful you grapple the opponent by impaling them, and otherwise it apparently works like any other grapple. It's a very odd skill though, so it's best to check with a GM exactly how they'll read it. Still... scythe grappler is just horrible and awesome.
A Dan Bong provides a bonus to grapple checks. Provided you can figure out how to wield one while still having 2 free hands. Alternatively, if you take the grabbing style feat you can use one w/o penalty.
