There's a saying 'familiarity breeds contempt' and it goes double for razors. Let me explain.

My most used razor is a 6/8 Joseph Rodgers frameback. It is as curved as a banana. I really love curved razors.

I am currently honing razors for one of our fellows here, and 2 of these razors are as straight as a ruler, and they end in a spike point.
When I say spike I really mean spike, as in 'an almost perfect 90 degree angle that begins right on the edge'.

Normally when shaving my cheeks and jaws, the point of contact with my skin is at the heel, and as I progress, I raise the heel to make contact with the middle part of the blade, and a bit more to make contact with the toe. This works perfectly fine with curved blades, and it allows me to shave every part of my face with optimal contact.

The problem is 2 fold...
a) this only works with curved razors.
b) shaving rituals become an ingrained habit.

So when I testshaved the 1st blade, I cut my skin at the cheekbone on the right AND on the left, and cut my ear on the left as well, despite the fact that I was really paying attention after drawing first blood.
The second blade left me only with 2 cuts. Again on both the cheekbones.

I have honed and testshaved a variety of blades, both in sizes, grinds and points, but this is the first time that the point is not where I think it is on my skin. each of those 5 cuts was made with the point only.

It's like learning to shave all over again.

There goes my winning streak of having no significant cuts for several months now.
