I know that blades come in a variety of widths, but do they come in a variety of lengths? The ones I have are typically around 3" long.

I would like to try a blade with a shorter length.
Why? Being a Newbie, I am concentrating so much on the middle section of the blade (which is in contact with my face) that I tend to nick myself with the tip. A shorter blade would help me overcome this, whilst I am still learning.

I have thought of trying one of the shavette type of straights that take standard razor blades to see if this theory works in practice.

Any thoughts?
