sorry Giga..i didnt mean to come across strong. i meant to emphasise my point because it's dangerous to start having any violence near your hands. ive known alot of people who have done crazy things that thye thought were cool or sensible and they loose fingers, ears etc. it's a reason we insist on no stabbing in the back. we do teach you how to stab in the back properly..but not so you can...so you know how to safely handle a situation if you see what i mean.
in the UK it's popular to now research old sword fighting manuels that have survived history (manuels written by pimps and brotherl owners not to mention gamblers etc). but anyone thats been fighting for real..for a while can see how stupid and dangerous these manuels are. however, theres many others who seek fame and infamy who belive these manuels are everything....the same people also belive in hurting their friends when sparring and fighting with them. as a rule of thumb i say "we all want to play, and most of us have to go to work the next morning, so lets play safe and proffestional."
when your parrying and blocking, most of the oncoming attacks should be cought around teh middle of the blade, on the flat if possible. a block stops a blow solidly, a parry carries teh blow on and away. if your fighting well, your quillions will actually not be touched much.
