HOW DID YOU ARRIVE AT YOUR STANDARD RAZOR HANDLE SHAPE?
When I began building custom razor handles, I engaged a series of focus groups to provide feedback on a variety of handle designs.
The initial group reviewed 8 separate designs and were asked to shave with each for a week. Surprisingly, the ornate handles fared poorly in the week long test and the overwhelming favorite was the “cigar” shape that has become my standard. The shape was equally preferred by those who primarily grip the handle close to the head, as well as those who grip nearer the base.
Once a shape was determined, the next group tested varying degrees of profile, ranging from an almost straight 2 degrees of profile and incremented up by 2 degrees to a max of 16 degrees. These test results were a bit more variable. I expected the variance to correlate to hand size, but it was purely a personal preference. The results did heavily favor a grouping that only varied by 4 degrees.
So, most of my handles will fall right in the middle of that 4 degree “sweet spot”. Some will be a bit more broad and some will be a bit thinner, just to add a little variety.
