Blender – Handy Weight Edit V1.2.2

Handy Weight Edit is an alternative weight painting method in Edit mode. 

It offers precise control where and how weight is distributed. Instead of painting in hard to get areas with brushes, you can now select individual vertex and adjust the weight value. Along with all the familiar tools in edit mode like loop select, xray, lasso select, hide/unhide elements, it is never easier to modify weight values during character skinning process.
