Recently, I have seen an increase in requests for second peg holes (mekugi-ana).

 

Although one would think that two pegs would be better than one, at best, a second peg has no effect, and, at worst it can jeopardize the structural integrity of the tsuka and shorten the handle's life span.

During a study session, Takahiro Ichinose explained that on most long swords the mekugi-ana is around "3 finger widths" from the tsuba, which is the pivot point, or point of least stress during most cuts. The further away from the pivot point a peg hole is, the greater the strain on the peg (mekugi).

The only type of truely Japanese mounts that I can think of with two pegs are the Late War Type 3 Gunto (in a katatemaki pattern), see:  http://www.h4.dion.ne.jp/~t-ohmura/gunto_005.htm

 

It has only been  in the last 10 yeas that I have seena lot of "Japanese" (but not really) swords with two pegs.  All of them are modern reproductions like from Cheness and Bugei, or those coming out of China and Pakistan.

To illustrate this, I have included an old diagram scanned from my personal notes written back in `88. It outlines Mekugi-ana stress, and explains why a tsuka with one hole has fewer fractures, a longer life span, and is more reliable than a tsuka with two

Does this make sense to anyone aside from me? Why -or- Why not?
