in my experience I have found that my shaving experience is directly correlated with the cutting sharpness of the blade. The blades I own that were on your list and my shaving experience went up the chart in the exact order. I think this is a great video and worth looking at.
Great to see your experiment. Forget whether the results are useful or not, what I value is , different way of thinking and off course nice to see your scientific temperament. All the best for your experiments and wet shaving both 😊
This was fun! If you're ever looking for more blades to test this with, I'd recommend Feather Hi-Stainless safety razor blades. Those are by far the sharpest blades that I've used.
No feather!?!? The best blade hands down is a feather. I love my murker 34c with a feather. I don’t like the German blades but Germans can make a great safety razor for sure. I use my feather safety razor with a feather blade now but it can’t beat the murker no doubt,
Thanks a lot! Never heard of them since they did not come in my package but I will try them out :) Just a few days ago I added the Merkur K 933 for traveling and I love it too...
Interesting approach to have a systematic way of measuring effectiveness of the blades. One thing though, when we shave, the cut is perpendicular to the blade's edge. The test you administered is along the blade's edge, much akin to using it as a surgical blade to cut than to shave. I wonder how the test would end up giving a result that is not totally in line with the effectiveness of the blades used for shaving.
Very interesting to say the least. A very nice durability test, even if it is the opposite cutting motion from shaving...the results are what you would expect for the most part. Nice control measures for the same razor, angle, weight, etc. Just remember that different blades acts differently in different razors and on different hair types. Also, I think Voskhod packaging is the best as well! Good video!
Would love to see some feather blades here as well. I was thinking would it help if you use more weight, not 100 but like 200 to 400 grams, if there would be more cuts it would be more easier to say what is better than other, but huge thank you still from this video.
maybe test again with the razor blade being pulled over paper/material perpendicular to blade then grade under magnification damage done to blade you can use the blades which you tested already by using the other sharp edge
could do if I had a microscope. My first and preferred idea was to use a electron microscope to check the blades before testing... But I do not have access to one :(
Just found your video as I'm looking for new blades to try out. I agree cutting things may not be the best representation of shaving but it gives some indication at least. Quite surprised the Wilkinson Sword didn't fair well, I love that blade I got in the UK recently. I'm not hairy but when the Treet last me about a month or two, the Wilkinson was about 5 months when I finally replaced it. I do like the black Rapira when I first tried it, definitely felt smoother than Treet. I was about to try the Astra but after your video, I think I'm gonna stay with Wilkinson, Rapira black and try out Feather finally. At one time I thought Treet was good till I tried Rapira, then I met Wilkinson haha. Thanks again for the video, it is still plenty useful though you did this a while ago. Cheers!
Both are excellent, but you might like one more than the other. The Derby Premium (Black) is sharper than the Derby Extra/Derby Professional(Green/Orange). The Premium is too sharp for some people. The Green blade pulls a little on the tougher parts of my beard but is also not as rough on my skin. So, if you are the sort who shaves very few days or breaks out, the green is better because you skin isn't tough enough to be beating up every day. The green is just about as sharp as the premium is after your third shave with he same blade. (Woman shave too.) Since somebody makes the Shark blade, we can be certain that some people learned to prefer a very dull blade. They are about as sharp when new as a Derby is when I throw it out, however, they also don't cause irritation. The Personnas are so sharp that they cut skin just as well as they do hair, so, for me, they aren't a good razor blade. Where I disagree with the reviewers test, the Wilkinson and the Astera are both made by Procter and Gamble. They are both excellent and may be too sharp for you. Since you seemed concerned about money, the Derby Premiums are at least five shaves per blade. Treet may be sharper, but most of their blades rust so stay away from that brand.
I think the experiment is malformed for the following reason. Your cuts are all angled. This means that like you described, the cuts are benefiting from sideways motion. This means that on the microscopic level, this test benefits the rougher blades (because the roughness is a bigger benefit going sideways). Also, it's hard to standardize your pull and your paper. Both are subject to a lot of random influence. If I were you, what I would do is put the blade into the wood at a 90 degree angle, and pull paper through... but of course, you would also have to change your measurement. You would possibly benefit from weighing the paper down and seeing if the weight is able to make the cut. However, there's a different test that is generally considered standard for measuring blade sharpness. You set up a jig that holds a wire, press directly down on the wire, and measure the force needed before the wire is cut. Sidenote, most agree that the sharpest blade you can get is the feather. So if you run another experiment, make sure you include a feather blade. If the feather doesn't score at or near the top, you can rest assured that it's an imperfect test. I enjoy these kinds of experiments, but at the end of the day, cutting paper or wires doesn't really tell you what will cut hair... and even moreso, it won't tell you what will cut YOUR hair. It's actually quite complex what kind of razor you should be using. If you have thick and dense hair, you might benefit from a sharper blade. If you have sparse and thin hair, you will probably prefer a milder blade. Not only that, but if you are shaving after a shower when you are perhaps even overhydrated, you are going to want a dull blade (because not only is your hair hydrated, but so is your skin. An aggressive and sharp razor is gonna scrape off a thicker layer of skin when you shave). If you are shaving after wetting your face for just a second though, you can likely use a sharper blade since your skin and hair are likely to not be overhydrated. Something I've been trying lately, oil hydrate instead of water hydrating. This gives you better glide and protects your skin, so you can use a sharper blade (I use a feather) and cut the hairs really close. It's also a very fast shave. It's actually quite complex. lol
A proper way to do this test is to show the blades under a microscope before and after shaving so we can compare the damage done to the blades after each shave

I've also used those Feather blades with a sliding microtome in a lab to make thin sections of biological specimens 😃
Well done sir. I enjoyed watching this.
I've tried so many brands of razor blades, nothing come close to that blue original Zorrik , they are so sharp and smoth and last very long time.

I don't like feathers.
thank you for this. wonder if you could upload results in a google sheet it would be easier to see comparisons
Fantastiche! I salute you, sir.
Shark super chrome are my favourite blades.

Keep the Astra, Personna , Rapira and Voshkod . Then take all the rest and throw them in the garbage.
Personna sucks! Van Der Hagen is better than Personna.
Is rapira really good?

Where’s the Feather blades ? I really know what blades make a good paper gullotine now !

Nice organizing tray. Where did you get that?
I think I just printed it from thingiverse. Something like that: www.thingiverse.com/thing:3764805
what about feather blade ive heard they last very long
Unfortunately they were not included in the sets I got. I will look out for them

Nice
From my experience, Feathers and Personna are the most durable, the rest are more or less the same.
Best blade in my opinion is the feather from Japan. Looks like the only one you didn't have.
useless test. cutting hair is more like cutting wire not paper
