Suwon Crease

The Suwon Crease

Korean Scientists Identify Rare Heart Line Formation as Suwon Crease

You may have heard of the Simian Crease, a line on the palm that transverses the hand from one side to the other.

The simian crease has been identified as a single crease crossing the palm in place of the usual two, the heart line and the head line.  In the scientific community this is seen as both, a single crease as well as a complete joining of head and heart lines.  Sometimes you’ll even see remnants of a heart or head line which are involved with the simian crease.  Those with remnants are categorized as simian variants.  This crease is found in normal hands but also is common in relationship to syndromes such as Down’s Syndrome.

Another crease that is familiar in both the Palmistry and Scientific communities is the Sydney Line.  So named because it was first identified by researchers in Sydney, Australia.

The Sydney Line is a crease that is described as a head line that crosses the palm all the way to the ulnar edge, or little finger side of the palm and a heart line is also present.  At first it was accepted as such if it only passed a specific area under the little finger, but after studying the crease when it formed in relationship to birth defects the definition was more strictly defined to reaching all the way to the ulnar edge of the palm.

The Suwon Crease is sort of the ‘cousin’ of the Sydney Line. It consists of a long heart line that crosses the entire palm appearing to join a head line at the radial edge and a second head line present.

This newly identified crease is called the Suwon Crease because the researchers who ‘found’ it have named it after their location in Suwon, Korea.

Earlier researchers made note of the existence of this crease but didn’t further clarify it or give it a name.  It was more or less a Simian Variant. (1)

Formulas are presented as:

  • Life Line  I  Radial Longitudinal Crease
  • Head Line  II Proximal Transverse Crease
  • Heart Line  III  Distal Transverse Crease
  • Simian  II + III  Joined Head and Heart Lines
  • Sydney Line II + III with Accessory III Joined Head and Heart Lines with extra Heart Line
  • Suwon Crease II + III with Accessory II Joined Head and Heart Lines with extra Head Line

Although the name Accessory implies secondary in the sense of less important, it is only referring to it being a second or additional head line, or in the case of the Sydney Line an additional heart line.  This is because the long transversal crease is thought to be a joining of II and III, the heart and head line.

The Suwon Crease is even more rare than the Sydney Line. The Korean researchers found it in 0.5% of 5,196 hands. More commonly found in the left hand of males with zero percent (0.0%) of females were found to have it in the Korean study.  Looking through my collection of hand prints I found a female with a Suwon Crease.  See below.

Do you think you have a Suwon Crease or other unusual combinations of the head and heart lines?   Please feel free to reply below and I’ll let you know where to upload or email images of your hands for verification.  Or, visit this Facebook Page: “Hand Analysis of the Future”

I have been gathering feedback from people with these formations for several years and will be consolidating the responses and sharing them here in the near future.
