Is the height of the stand throwing you off? The things are very simple to put together yet it amazes me how many enthusiastic don't take the 20 minutes to get a platform sorted out. Even if it takes a few tries it's worth getting it right. I've been using my garbage/Recycling bin with a piece of a wooden desk top to cover it, so I don't hit my garbage cans. What cutting stand do you use? BTW the swords in question that bent are the Cold steel napoleon saber, 1796 light cavalry saber and Windlass Shasqua. Yeah, that's a pretty non-optimal setup for cutting. I did the same thing and my cutting suffered for it because I was too afraid of hitting the can, and the size of the stand compared to the target really restricted what kind of cuts I could make well.

In this video at 3:29 skallagrim puts a set into a rapier (and doesn't notice) by flexing it beyond reasonable measure. It comes out somewhat when he does some more flexing but that spot now is going to be a major weak point.

I cringed so badly seeing how far he bent it and how it stayed bent... Why would anyone do that (sorry skal, if ya see this. Your channel is great. But that poor sword...) I woukd have just shortened the blade to make it stiffer

Since we are on topic, my gsow has a slight bend a few inches past the fuller. Bending it over my knee doesn't do much as it has a super good temper. Any advice how to fix it? Or should I just accept it as a quirk

Or should I just accept it as a quirk Matt Easton has a, possible two videos, on blade straightening. I think two. One in which he breaks his work bench doing so. You will have to search for the video as I don’t have time at the moment. Thrusting with a bent blade might be asking for trouble.

What cutting stand do you use? When I started I used a plastic stool to support an old coffee maker and placed my target on that. A cutting stand is much better. At the time I found several plans and I just made a brief search and found nothing satisfactory. If you look at cutting videos you will find what people are using. You can also do a search. Below are two photos of mine. It is 30” high and works much better than that stool with coffee pot. Hehe Sitting here thinking back on that coffee maker makes me think, while not all that satisfactory it did help me with cutting skills, more so than that cutting stand, because the top was slightly domed and slick if I was off with technique the target would not remain on the maker.

Thanks for the responses.
Does anyone know what the hardness of the steel needs to be in order to return to true?
From my research, most longsword reproductions are tempered to HRC 50-54 Rockwell. Is 50 HRC the minimum hardness needed to return to true? The reason I ask is because I've seen videos of blades tempered to less then 45 HRC bend and take a set.

It depends on the alloy. For the lower carbon ones, best spring performance can be at about 45HRC. Higher carbon steels can give their best spring performance in the low 50s.
That's assuming a good fast quench. If the low hardness is from poor quenching more than tempering (i.e., re-heating after quenching to reduce brittleness/hardness), it will tend to take a set easily. Also note that the hardness of the blade won't be uniform - the edges will usually be harder than the core. For a thin spring, the hardening is more uniform.
If doing primitive heat treatment on springs, the rule-of-thumb is to temper until the steel is deep blue. Thus, heat-blued swords, if deep blue as many are for maximum contrast with gilded bits, should be close to optimum spring temper.
