When I was a kid in the mid-70s / early 80s, my mother, my brother and I would go every sunday and visit my aunt and uncle and cousine.
My uncle had a Betamax-videorecorder (VR) and a lot of (original) cassettes for it.
When the grown-ups were tired after lunch and they wanted their peace from us kids - we were allowed to watch movies on my uncle's VR.
On these sunday afternoons, I watched a lot of movies, that I learned to love (many of these movies definitely
not suited for 6 to 9 year old kids, but hey - those were the days).
Besides the entire Bud Spencer and Terence Hill movies available at that time, lots of (now) classic western, all the classic Godzilla stuff, disaster movies, adventure movies, sience-fiction movies like Atragon and Latitude Zero, etc.,...we also watched a lot of eastern (martial arts, wuxia) movies.
One of these movies was "The new one-armed swordsman" (a.k.a.: Three Irons).
A true classic, which I can only recommend to any MA-movies fans (the few, that don't know it already).

EDIT 19.05.18:
I found the movie! :D
After searching the net for the last few days, I stumbled over some site, where they streamed full movies.
I switched through their program, and - believe it or not: there it was - simply so.

Reading the movie's title alone, made my memory tingle.

Then I started watching it, and knew immediately: this is the one!

German name is "Ching - Das Geheimnis des schwarzen Schwertes" (alternative German title: "Ching - Das Geheimnis des blutigen Schwertes").

(engl.:"Ching -the secret of the black (bloodied) sword")

Official English title: "(The) Darkest Sword", 1970 /Taiwan

My memory screwed up the story a little.
The guy who loses his legs, actually gets killed by them himself.
And the blades were not set inside the bones, but slid out of the protheses' soles.

However: my memory was right in some way, also.
Because in the movie, there is also a golden sword, and it gets used for vengeance.

Awesome! :)
EDIT-END

To give you an example: "The new one-armed swordman" was called "Das Schwert des gelben Tigers" (the sword of the yellow tiger) in Germany, but for years, I had (for whatever reasons) the title "Das goldene Schwert der Rache" (the golden sword of vengeance) in my mind.
Now, as you might imagine, that didn't help with finding the movie.

And now I guess, that maybe (in the German title) the words "golden" and "vengeance", might have something to do with the movie, that I look for, and that they crept into my memory from the other movie title.

However, the description of movies like "Das blutige Schwert der Rache" (the bloodied sword of vengeance), or "Die Rache der gelben Tiger" (the revenge of the yellow tigers), doesn't really ring a bell.

So - any kung fu / martial arts / wuxia / eastern - movie fan present, that can help me?

And here is a scene:

Well, ok...my fault. ;)
Maybe I should've mentioned, that the movie I'm looking for, was set in medieval (?) Japan (or maybe China).

But thank you, nonetheless! :)

You mean there is more than one movie about a martial arts master without legs? XD

I should have known.

Of course, there are:

;)

That movie was going to be my next guess.

Nah, unfortunately that's not the one.

Sorry, no idea. I wish I could help (kung fu movies are awesome!).

You may want to ask these guys, though.

Thank you for the link.
Maybe I'll give it a try some time later - but right now, I don't really want to open an account, just to ask about one movie. ;)

Take a look at "Crippled Avengers" and "The Battle Wizard". Either might be the movie you are looking for.

Thank you!
But, no - it's none of these, unfortunately.

It's a shame PheonixWright isn't around here much now. He would be able to answer this for sure.

ho boy, this could take awhile. with those two scenes and two actors it could be a number of films. It's almost like trying to pin point the name of a early Italian Cannibal film staring Me Me Lei where she plays a native tribe woman who gets butchered and eaten by cannibals towards the end of the film.

I'll see what I can do, I'll try and trudge through my films and see if any of the ones I have match up and if that fails I'll just ask a few people I know like Video Bunker's Chris Yardley or my little brother's podcast co-host Steve who saw most of these films and others in the theater and has quite the memory and if that fails I'll try the boys on the Grindhouse Sleaze and 80's video trash facebook group, I mean if they could figure out the movie Demon Wind based off me just asking for the name of a 80-90's era VHS film that was a bit like a cheesy evil dead which has a scene of a "Priest summoning damned souls to him and turning into a blister monster who bites the neck of a woman and reduces her to a bloody, flesh chunk covered skeleton", Someone will probably figure out what movie your talking about.

I'm actually surprised, that not more people have some ideas - I considered the crowd here as pretty well informed, when it comes to all sort of "special interest" - topics.

But maybe most people here are too young, to know this movies? (or too old to remember them) ;)

I just want to make clear: I'm nowhere near sure, that Ti Lung and/or David Chiang are really in this movie.
I'm also not sure, that this movie is from the Shaw Brothers.

As already stated: I must have been somewhere around 9 to maybe 12 years old at the time - at most.
So, my memory of the actors involved is naturally not the best (their names were of no interest for me, at that age)

Of course, the fact, that they (SB) made over 800 movies, doesn't make the checking easier. :)

But I really appreciate any help!
So - thank you in advance for your efforts. :)
