I am not sure I can attribute the title of "Best Feeling Handles" to any one maker. I have a Brett Gatlin Bowie with a wonderful ergonomic, palm filling contoured handle, a contoured and grooved Bowie from Shawn McIntyre, a utility from Dan Farr, all of which feel great and demonstrate the benefits of working the handle.
But equally I have some unworked stag carvers by other makers that seem to be perfect due to their proportions and gripping texture ....... Balance of the knife, and the size of your hand also play a big part in it aswell as the handle shape.
As an aside I am always surprised by how comfortable the angular handles can be such as those from Bailey Bradshaw, Hudson, and generic designs such as the Dog Bones, the angles give purchase and security in the hand.
Cheers,
Stephen
