Tom, you continue to make me think and learn. You know so much about the actual construction of blades. Acknowledging that, let me ask you if this aspect is a substantial variance in construction; most of the SEA "swords" that I've seen have the base of the blade and the tang held in place with a form of pitch, even the ones from central Thailand, however most of the "dual-use blades" that I've seen have a brass or iron ferrule hammered down over the wood/rattan handle which holds the blade in place through friction and many have had shims hammered in to tighten them up. Is that a significant difference?
Montino, screwdrivers DO make excellent throwing knifes, as my Grandfather's garage door can attest to (my first experience at woodworking shortly followed)
Mark and Andrew, you've been holding out! Give up the bibliography or I'll hold National museum database hostage

A final note on quality, as an old business teacher once told me "Quality is measured in the delightment of the consumer".
