Bricklink has a fairly good comparison.

BL describes 3847a as "rigid ABS", it is shinier and the edge line on the blade seems more prominent.
While the 3847 seems to be from a softer plastic and had a duller surface.
But that is not something we can influence as don't have material/surface properties.
