i seem to have a slight problem with both of them and i wanted some advices.
the problem is my blade seem to have problem to enter his original saya and i would like to know if my blade has taken a slight set, is there a way to perfectly see if a blade has indeed taken a set?
also if it is a saya problem how can i fix it?

Possibly if you have been cutting hard stuff with it. Or it could be humidity, warmth making the saya wood warp. I know like 4 of my sayas that were always nice fitting are now all loose .. at about the same time the weather changed here.

my saya is not really loose it's the blade that have problem (i think...) it's as if the kissaki was grinding the interior of the saya at the middle.... and also it might only be my way of resheathing but the habaki seem to stop the blade just befor entering the saya (just for the image imagine a car accident where the car hit a cement border with one of the front side) i just need to rotate the blade a little more to have it in the saya without the annoying *clac* of the habaki hitting the side of the saya interior. it may be only due to the humidity as my windows are wide open and the air is very humid... but no problem with corrosion fortunately

it seem the problem is my blade is has taken a set! probably from when one of my friends used it to cut a hard plastic bottle swinging it like a baseball bat (i cut through that easily with the same sword but he couldn't :lol: no good edge alignment)
i tried to replace it a little using hot water to make the steel hot and rebend it to shape but the "$&#%+* don't want to come back it always return the bent way... well if i was able to cut with a bent sword perfectly it must be ok... i used a kitchen table to see if there was a set just need to make the blade stand on the shinogi-ji with two fingers and that's it (don't know if this method is a good and precise way to see if there's a set though...)

That's a bummer. I was going to suggest checking to see if there was some foam or cloth in your saya with a coat hanger wire but the blade is bent, eh? You should be able to detect where the set is, just looking down the spine. Try clamping the blade down on a table top, wrap a towel around the part you need to grip and give it a go. Just be careful!

I have 1045 katanas that I've flex tested to about a 30 degree bend and they return to form just fine. Properly heat treated steel will still be able to 'spring' back to shape- it doesn't have to be a 'spring steel' (although I don't know just how far each steel type can be bent without deforming)

yesterday i tried to return it to true form (without a set) but it was always returning and i feared that if i was trying too much i would break the blade... it could be a properly heat treated blade but my friend (the one who used it) is really an iron breaker (it's just a literal translation of the french expression ''brise fer'' but i don't know if that term exist in english ^^')

You should be able to get that bend out. You just need to loose your timid fear of messing it up more. The steal will take it don't worry. Clamp it onto a good solid table bench whatever where the bend is, and give it a few good (safe protected) slow pulls in the correcting direction. Any bend that occurred by a bad swing on a plastic bottle is a bend you will be able to pull out without a worry. You just need to not fear your blade. Protect your hands, and give it a good pull. Really your 1095 will flex and that you hae been having the bend just return, means your not giving it enough mmph. If you need to, google sword destructive tests, and see how much many of the swords out there really can take. Many blades can take close to 60 degrees of bend and return to shape. Good luck.

in a book of seitei toho batto do there was this way of straightening a blade but they also said that you must heat the blade a little in order to soften it so it can be brought back easier is it the truth?
by the way thanks i forgot this way and im really worried about destroying the blade i think i'll have to try it anyway ^^'

i tried it and i guess it wasn't bent maybe just an illusion because of the nakago and the place where the yokote is...
i don't know if you understand but the blade is made a little like this ''()'' the tip of the nakago is thinner and the thickest part is where the cutting edge begins and then it retapers to the kissaki. from what i've seen for now it isn't bent at all so i guess there shouldn't have a problem at all!!!
but...
i took a look with a flashlight in the sayato see if there was something and now i have two hypothesis...
1-there is still something in the saya 2- the saya is carved flat at the end (not following the kissaki)

Well good to hear your blade is not bent, I was a bit surprised by the idea someone might have bent a blade enough to cause saya problems with a water bottle cut.
Have you checked your habaki? If you habaki is off center, either side to side or up to down it could cause the trouble you were mentioning. Personally that was the first thing I thought was your trouble, but you insisted it was a bent blade. I would suggest you look at the habaki and see if there is a misalignment there. Even if you don't see it, try removing the habaki and checking. Was it loose? Is the hamachi (where blade edge meets tang) damaged? Was it on wrong? Is the habaki damaged/cracked? Does taking it off and putting it back make it fit better? The habaki would be my first place to look then from there if there is nothing you can see wrong with the habaki I would consider probing the interior of the saya. With a wire hanger or some other sort of thing, to see if maybe a piece of the saya cracked inside and is rubbing.
With out pictures it is hard to guess, but from your initial description my first guess was habaki trouble. It is funny how that little brass collar is so important to everything in the katana fitting right.

i don't really think it is a habaki problem it is tight (i need a wooden hammer to remove it...) and because of that the alignment is perfect.
the alignment on the BLADE is perfect but in the saya it is another story kind of sucks i wonder if it would be less trouble changing this saya for a custom one but it's pretty expensive...
i'll try to snap some pictures of the blade in the saya and of the mouth of it.
