Notice that the part of the plane block (the dai) which is pulled towards you is referred to as the daijiri (the 'butt'), while the part on the other end, furthest from the user, the the dai-gashira, or 'head'.
The plane pictured is the exclusive kurisuhoru signature model, in unobtanium steel, forged on the rare occasion of the 13th month's full moon..

The tsutsumi treatment is usually found only on high class dai for finishing planes with a very tight mouth opening. Such plane blocks are termed tsutsumi-dai (包み台), or, tsutsumi-guchi (包み口). Standard plane blocks without the ledge are termed futsū-dai (普通台) and are perfectly fine for use and less hassle to set up and tune.
Preparing/adjusting the tsutsumi ledge surface properly is done most conveniently with a special crank-neck chisel, like this one:
