Thanks for answering the basher's posts. I couldn't have replied better due to my English speaking and writing level, but I'd have said just that. I believe that even though history taught us many useful things about edged weapons, and their best uses and applications, it is not realistic/practical nowadays. Not at least in our developed society. You can't carry saber, or a 14 in. Scottish Dirk on you.
Sure I'd rather fight off an attacker or a crack-addict on a violence rampage with a foot long Kukri, but I understand the reality behind the idea of wearing a two pound, one inch chunk of steel on my belt on me while on the bus or going to work.
Or concealing a Cavalry Saber on my person while sitting on my car, seat belt on, asking for a couple Burgers at McDonnalds.
Maybe not as effective, but "fighting" knives nowadays allow for safer/better grips, more concealable and reliable sheaths (molded plastic, kydex, multiple position carry clips), stronger and more durable steels, lighter weight and construction and an extremely extensive catalog of blade sizes, shapes, styles and characteristics available at a reasonable price, no need to have a bladesmith make it for you.
So, yes, Fairbarn-Sykes might have created the deffinitive stabber, Bowie the ultimate fighter, japanese bladesmiths the best cutters and slicers and European warriors may have done the deadliest battle weapon, but all those where tops
at the moment they were built and having in consideration
the society of their time, so there's no real jack of all trades for every scenario.
That's why I suggested the Hissatsu. Perfect application of modern materials, ideal steel in corrosion resistance, toughness and ease of sharpening (no need of armor piercing or steel bashing here), reliable and discreet synthetic sheath with multiple carrying options...and what is also very important: disposable, cheap, readily available and with a trainer version to practice all day long.
