Having now used the Rocca V4 for several weeks, I find the razor smooth and efficient, definitely much smoother than my previous V3 Rocca's. With the switch to full CNC machining for the top cap and base plate, it appears V4 of the Rocca has finally solved the problem of poor manufacturing tolerances, that so many users experienced with V1, V2 and V3, MIM (Metal Injection Molding) Rocca's - not before time. I always liked the Rocca's balance, well judged weight, voice and tactile feel of the birch-bark handle and am now delighted with the quality of the shave.
The main differences between each version of the Rocca appears to be:
V1 = MIM (Metal Injection Molding) top cap and base plate.
V2 = MIM top cap and MIM base plate (MIM circular flow marks polished off the underside of the top cap) blade posts and centre post are glued / welded onto the top cap rather than a complete MIM mold, as V1.
V3 = MIM top cap (complete mold with visible MIM circular flow marks on underside of top cap; no glued / welded centre post or blade posts) with CNC machined 316L stainless steel base plate. Base plate re-designed - now with narrow centre channel.
V4 = CNC machined 316L stainless steel top cap and CNC machined 316L stainless steel base plate. (I am assuming "CNC machined top cap" includes the centre post and blade posts in the machining; but I do wonder if my assumption is correct after the surprise at how V2 heads were manufactured).
Muhle have finally got it right with the V4 Rocca, it is now a great upper medium efficient shaver.
