I would like to ask how to correct the steel scabbard with a 1-2 degree side bend. It's too hard, I don't know what tools to use to correct it without damaging it.

Can you show us how it looks? And how did it get the bend, do you know? You could try some clamps, lock it in place before the bend and put a screwable clamp after it and screw it against the bend until it is straight. I would put something inside so it does not collapse, like dowel rods. And on the clamps you should use something soft like wood or leather. I am not sure if youn get what I am saying, not sure how to better explain. The scabbard being hollow makes it more tricky than straightening a bar or sword.

I've tried tapping the sheath with a rubber hammer before, but as you said, it's hollow, so there was some slight deformation. I immediately stopped and posted this post seeking help. I have prepared wooden blocks and G-clamps now, and I am considering tightening the G-clamps to compress the bent parts. But I don't know what kind of support should be used inside the scabbard to avoid any indentation.

I would shape the wood to the scabbard a bit, the bigger the area of pressure the better. And go slow, you can see if the steel buckles. Another thing you could try if there is no leather/wood/plastic inside is to heat the metal a bit on the side that is concave while you bend. This will make the metal move easier and expand against the bend (do I make sense?). Don''t go above like 150°C though. The bend looks quite concentrated, so the less space between clamps the better EDIT although it will take more force that way, maybe better fix the ends as far abart and put slow pressure against the hump of the bend, I am not sure.. You could try something like this with 3 points: (I thought the end was bent off to one side, not like a hump)
If you can get the throat of the scabbard off you could use a wooden plank of the right size to shove towards the bend and begin straightening and shoving the wood in deeper until it goes through, have you ever seen how brass instruments are repaired? You could try this if the scabbard buckles. Brass moves easier but with some perseverance it also works on these mild steel scabbards.

The scabbard is too tough. I padded the ends with wood blocks and pressed the bent part down with a G-clamp until it bent in the opposite direction. This process lasted all night, and in the morning I removed the G-clip and the scabbard returned to its original curved shape.

This process lasted all night, and in the morning I removed the G-clip and the scabbard returned to its original curved shape. I have no idea, if you are going to read this, but I had to straighten a scabbard a tiny bit, I inserted a rebar rod so deep that the edn was at the highest part of the bend, fixed the scabbard with clamps at the other end of the bend and used the lever of the rebar. It worked, but my bend was relatively close to opening of the scabbard, the deeper it is the more difficult it will be. You have to take care not to bend the scabbards opening, it worked, but it was only a few millimeter for me.
