Hello! Been gone for a while from here, been in the buisinnes for shorter, but still insane sharp, things I made a video where I cut an A4 paper in two without holding it! As you can see, I have let go of it when the knife hits as they fall down together! The knife I'm using is a Fällkniven K1 kitchen knife in laminated VG10, sharpened and convexed by me. It can easily cut an empty water bottle in half, maybe I'll make a vid of that too some day When the snow melts I'll go mad with my katana and some knives on the pile of waterbottles I've been collecting all winter

The thing about cutting paper, if you have a slicing motion even the dullest knives can cut paper. Try it and you'll see paper cuts with ease even with a dull knife if you are pulling it through the cut.

Try it and you'll see paper cuts with ease even with a dull knife if you are pulling it through the cut. I disagree. If I'm wrong please demonstrate it. I have had zero success cutting any kind of paper with a clean slice and no tearing at all without having at least some kind of quality edge. No matter the technique. I would say most kitchen knives may be able to do this if they have a good serrated edge, too. Though I'm not 100 percent sure in what I'm saying, too... Thin paper is weird stuff. For me anyway, the thinner the paper the better test it is for an edge. Thicker paper, at least IMHO, adds some resistance back on the knife or sword. Like how a so so edge can cut junk mail all day long, but fail cutting cleanly into one thin sheet of paper.

Msmalik: I agree a bit with you! But that's just if you hold the paper and slice very close to your hand! And a dull knife slices a bit, but when the paper starts hanging loose on one end it gets clogged and starts ripping instead of cutting.... And the thing is that when the knife hits, the paper is already falling down, I don't hold on to it at all! And that's something not even my sharpest hunting knives can do, even though they give a perfect cut when I hold the paper! A knife that's not sick sharp just gets clogged and pulls the whole paper down. Nuclearkittens: Thanks

If you want to see if your blade is sharp throw a square of silk into the air and try to cut it

Msmalik is 100% correct. Owning 5 swords and the tenchi (dullest 300$ sword ever) being one of which, I have no problem with any of them with the pulling technique.
Also, there are vids out there of people cutting paper with a bokken... this video is off of Deb's thread on gumdo practitioners:

I'm still trying to understand this from a scientific mind set, though. I'm having a hard time seeing how that guy can do that... I few factors would be the edge on that wooded sword, ie if it's more pointed vs round. The other factor I'm thinking of is the paper they are using. I'm having a hard time understand how our own news papers in single sheets hung like that could cut with a wooded or dull blade. Now...I think I need to do some testing and see this done in person. lol. I'm blown away by this.

Ok guys, holding a paper in one hand and drawing the knife towards you to saw off the paper can be done by most knives, but absolutely not all.... But any knife can NOT cut a paper without holding it with your hand! As I said, when the knife hits the paper I don't hold on to it, it's falling free! If I pull the blade towards me more than very little when I cut i just drag the paper backwards! Plus I haven't got the blade length to pull long enough to cut an A4 paper just by pulling.... And if it's still unclear, look att the video to see I'm not pulling... Any videos on the silk cutting Bloodwratith suggested? I guess it isn't like in the movie bodyguard

Cutting newspaper with a bokken of any type is not so hard, I had a go at it with my bokken the other day and made nice clean cuts except for the wind which made the paper jag on the blade. I didn't try it with my other bokken maybe at some point. Might be able to take some really bad video if I can get the weather to behave. Cutting paper with a knife is harder if it is free hanging paper with no resistance.
Rickard: I haven't come across any silk cutting demos yet, it is a pretty demanding test because of the way silk is spun. If I ever get my hands on any I might have to try it, but nothing short of a true japanese sword would cut it.

Well I peg it up on a line with two pegs, single sheet and I cut it making sure that my edge alignment is perfect. Cutting newspaper with a bokken requires speed and edge alignment. You use much the same principles as when cutting bamboo or when making what I call a "standing" cut, where you cut through tatami and it continues to stand after you've cut it. It takes much skill to be able to cut evenly and quickly but that is what perfection is about.

blood, will any bokken do for the newpaper? I have a master quality oak bokken from ebogu, and it's very round... so are these cuts done with special bokkens or any kind?

Trevor: any bokken, nothing special. I cut with your standard run of the mill martial arts store bokken that cost me $29. You can even do it with a suburito if you are very good. The thinner the bokken the easier it is to do but a standard bokken will do. You can also cut it with a bo staff or even a wooden wakizashi or shoto.

the newpaper and bokken isn't so hard afterall, though I do suggest getting the creases out of the paper before cutting

Thanks Deb. Gave it a try with the pk light, after 30 minutes and alot of fustration I finally see how it's done with a real sword. You gumdo practitioners really emphasize perfect edge alignment, I'm gonna look for a school in san diego and take a peak.
