The first roll was on 2" thick newspaper roll with PVC shaft. Windlass 15th century longsword.
The second roll was on 2.5" thick newspaper roll with PVC shaft, Deva Slayer. The shaft was unable to support the momentum of impact and bent. The cutting stand's pipe was also broken under Deva Slayer's attacks.

Thanks Lancelot! I've been thinking of using newspaper like that, since tatami is outrageously expensive here. How do you find it compares? The longsword cut beautifuly, but I can't understand why the Deva Slayer didn't sail through equally well. Is it as sharp as the Windlass?
Thanks for the vids! Very Interesting!
Cheers

Deva Slayer is even sharper than the longsword. Obviously it was me who was the issue. HHAHAHHA I have to learn a new way to use it. A dragging cut. Just mastered it half an hour ago after my master reviewed my motion and examined the fault in the cuts. I found newspapers roll to be even harder to cut than tatami mats because tatami were heavier and provide more resistance. So I have to add a shaft in the newspapers. I'll practice more of the dragging cut and try again later to see if it makes any difference. It doesn't make any difference on cutting water bottles, but on something more resisting we'll have to see.

Interesting stuff, Lance. I have tried paper alone with mixed results. I'm going to have to try that. +1

Maybe we can see the vids! ;D Thanks for the info on the newspaper- I assume you soaked it first? It looks wet in the vids. Oh, and I forgot before, so +1 as well! Thanks! Marc E

Yup, the newspapers were soaked for a couple mins. Easy to prepare.

how bad does the PVC hurt the blade of the sword?

It doesn't hurt at all. The PVC I used was those that used to house electric cables. So the wall is thin and quite ductile.

How long to you soak the newspaper? I soak mine about as long as tatami, so about 20 h. I agree that it is harder to cut than tatami, especially if there is no core. Newspaper wrapped around a 2'' wood core are easy to cut with my tenchi but without, they often just get knocked over, if my cutting technique isn't absolutely perfect. Most important is the dragging move Lancelot mentioned earlier, especially if you are using a straight or only slightly curved blade.

I just sprayed it with water for 1 minute or less.

Tried again with Deva Slayer after learning the specific way to cut with Chinese style. Very successful.

Very nice, Chinese Dao techniques work very well for "chopper" type swords.

Is it just me or does the Chinese style cutting look similar to Japanese style cutting?

It can, but there are some technical differences. Also, it depends if you are cutting using an external Chinese style (ie Shaolin based martial arts) or an internal Chinese style (ie Xingyi, Bagua, or taiji) as the mechanics of both styles are quite different from each other. Chinese hard arts tend to look like Japanese hard arts or Korean hard arts the main differences being some technical handling based on differences between a katana and a dao. It looks like Lancelot is using techniques from that side of Chinese Wushu (martial arts). The dao is much more of a heavy chopper so I can see dao techniques being a little better suited for that heavy arse Deva slayer of his than katana techniques.

Test cut on unfixed 2.75" diameter wet newspapers roll and PVC shafted 3" diameter newspapers roll.
My student test cut with windlass 15th century longsword on unfixed 1.75" diameter newspapers roll.
Another student test cut with Martial Art Korean sword on 3 different diameter unfixed newspapers rolls.
