Does anyone have a reccommendation for removing dents for sword scabbards?

I've contemplated using elongated pieces of wood to insert into the scabbard to hammer out the dents.

Any suggestions would be appreciated.

BofB:
I believe some of the members here have made up dent removers for dagger scabbards out of mild steel. I don't know why this wouldn't work for swords as well. Understand that it would be a challange with a saber with a curved blade though.

I have been collecting since '97, and have observed several discussions on the repair of 'train car door dings', and dents in metal scabbards of swords and daggers. I have mentally built several devices that would involve either a balloon or a scissor-like contraption inserted into the scabbard. Problem is finding a bladder(balloon)long and narrow enough and then getting down into the scabbard without damaging it's integrity. The scissor, of course is old fashioned leverage. Problem here is the scissor blades are too long and thing to apply the pressure to overcome the dent.
So let's think outside the scabbard (or box)to seek the answer. It came to me when I was watchin' a body'n fender man pullin' 'dimples' out of a hail-damage car. He wuz usin' a suction device! He had a set of stiff cups of different sizes, with rubber-coated rings which he placed on the body panel and then hooked his suction device (I think he called it a Lewinski) to a nipple at the cup end. After 'removing' pressure you could hear the dimple 'plomp' out. He removed the 'lewinski' and Wah-lah! Smooth as new and no paint chipped or cracked. He musta done about 40 dimples in an hour.
So the solution for scabbard dings would essentially necessitate the same approach, only you would have to fabricate a custom-made 'lewinski' with a smaller, more elongated, surface attachment orifice, appropriate to a scabbard side panel. Not faced with the problem myself, I have not taken this out of the concept stage to build the 'X', let alone taken it to 'Y', but feel free to have a go at it.

I always thought going to an instrument repair would be best, they fix trumpets , etc. Tiep
