Thanks Tom
I found the angle on the v1 and v2 to work pretty well for me. The handles feel as though they could do with more curvature and this is exactly what I like about the v3 handle. I can understand why some people might find the straight handle of the v1 and v2 to cause a problem when shaving WTG on the neck, especially given that the edge of the blade appears to follow the same vertical plane as the foremost edge of the handle. I only ever shave ATG on my neck (WTG) elsewhere and didn't find any problems in this respect.
The v3 handle feels intuitive to hold and I suspect that were the v2 head to be superimposed on to the v3 handle, this would potentially hit a sweet spot in terms of shifting the head forward (in much the same way as a traditional injector does), thus giving a shaving angle that is much easier to find.
The v3 blade appears to be angled at a smidgeon over 270 degrees, whilst the v1and v2 follow a more traditional angle of around 247.5 degrees. This leaves the v3 blade to be positioned more or less perpendicular to the face and this involves a lot of work trying to angle the razor into a position where it will cut.
Hopefully, the above helps give some meaningful feedback.
