An interesting point, from an art point of view, one may wonder why this would put someone off. On the other hand, from an historical point of view, i can understand why it may dissuade some folk. For folk looking to buy good art pieces (by a good smith) at good prices, then i suppose it makes good sense to buy wakizashi, rather than the far more expensive katana. All the artwork is there, just shorter :D. The down side will be finding buyers in the future that think along the same lines. One question though, i presume Koto wakizashi blades where less likely to have been owned by merchants, would this be right?
