Great Eljay!! Here I thought I had this all figured out!!!
I would have to dig a bit to find those words cited, but after your beautifully supported rebuttal, I would hate to tarnish whoever it was who wrote them.
Naturally, with arms as with most things, there are countless exceptions for every rule and I must admit that most desperate attempts at neatly and concisely cataloguing, classifying and rigidly identifying certain forms are usually pretty futile. I will say however that Oakeshott, Norman and Mazansky did set some pretty reliable 'guidelines'. Even Norman however steered clear of blades due to the constant flux of trade blades and refurbishing using incongruent blade forms during the often extending working lives of sword hilts.
Thank you for the clarification, which clearly reflects the tremendous knowledge you have on these swords gained through decades of experience. Nicely stated, and it's great having your posts here!!!
All the best,
