World's Sharpest Swiss Army Knife! - More than Razor Sharp! - How you can do it 

A real Craftsman

I love the views through the microscope. That’s definitely sharp. Thanks for taking the time and effort to make this excellent video.

I think that some kudos should go out to the sharpener also. That level of precision should be helpful to most everyone to be able to sharpen almost any knife blade to extreme sharpness. Your Victorinox is probably the sharpest I've seen, good job Felix.

Impressive stuff Felix - i use my blade probably 3, 4 or 5 times a week and i sharpen it with a basic sweep and its good enough 90% of the time I'd blunt that right away, so a razor finish isn't necessary - but you're efforts to prove a point are mighty impressive

That was an excellent demonstration and a lot of fun to watch. That is indeed the sharpest Swiss army knife I have ever seen, good job my friend!

Just what I needed :)

Good job. I am obsessed with razor sharp knives. All my knives are raroz sharp, including my swiss army knife. I use only sand papers from 400 to 1500 degree of graduation. Only first phase of sharpening, I do on 400 paper on the hard base below the sand paper until forming ''wire''. All folowing phases of sharpening I do gradually to 1500 degree sand paper on the soft base below the sand paper.Then I use leather strap with polish paste like old barbers and finish sharpening on dry leather strap. The result is mirror polished, frightfully sharp blade. It is cheap and relatively long lasting proces, but I am very proud of it.

I am always amazed at how sharp the edge of the can opener stays on my SAK after five years of use.

Always a Big Thanks to you Felix . All the best for an Excellent Holiday Season. All the best in all future endeavors 2022 .

That is amazing, Herr Felix. I gotta get one of those sharpeners.

good result my friend, good. A greeting!

wwooww, you have taken sharpening a Swiss Arm Knife to another level, don't know what the Manufacturers think but I am amazed at what you have achieved, Well done Felix, Cheers Ian from England

This was a great explanation of so many different things relating to steels, sharpening. Wonderful. Thanks Felix and happy 2022.

Several years ago there was a guy on RU-vid that got his knife so sharp by hand that he could cut wet toilet paper and a hair like you demonstrated. Your point about the size of the granules in the steel is spot on. I tried dozens of knives, dozens and dozens of failed attempts. Then, one day I had success! Long story short, I found four different knives that worked. I showed it to my adult son so people would not think I was crazy. Of coarse I was probably crazy for trying it in the first place. :-) All my work was done by hand with various grade wet stones to a wet ceramic flat stone and strop with green compound. No machines. I was never able to cut a hair. - sad I tried the same experiment about 1 1/2 years ago with the exact knives and failed! Maybe my beat up hands have lost the dexterity? Maybe the TP was different? I have very sharp knives. They are NOT hair splitting sharp. That is a whole different level! I have never seen a SAK that sharp. Well done! Because of this video I thought for a second, I should give it a try again? Nope! I just stropped a few knives like I do everyday and got it out of my system! Again, well done. Thank you for posting!

Fantastic video. I have used the spyderco sharp maker for over 10 years and then a leather strop. It has worked well enough for me, however I now want to take my sharpness to this level. Thank you for the effort and time spent making the video. Merry Christmas to you and your loved ones.

This cutting of limp hair is amazing. Your sharpening skills are fantastic. The microscope views were for me an eyeopener, it makes sense why your blade is very sharp. Thank you for sharing.

This week bought Climber. 👍😃

Great Video Felix ! A lot of work to get a mirror finished all I want from knives is a working sharp knife meaning toothy sharp !

Thank you for sharing this technique. I was able to grind down the small blade on my Swiss Champ into a whittling blade as demonstrated in your other video and sharpen it to approximately 17 degrees on each side and get it close to the sharpness you reached. Your videos furthered my appreciation for Victorinox knives and are why I decide to carry the Swiss Champ with me everywhere over the Leatherman Wave. Cheers!

WOW! Like.... just WOW! Very good !

That is indeed Scary sharp Felix

Hello Felix. I am totally amazed at how sharp you were able to get the knife. I have never seen a knife so sharp. You have encouraged me to do some sharpening. Thank you so much for all you do for the community. Merry Christmas my friend.

Fantastic job Felix! Today I decided to sharpen the large blade of an old Victoria Officer. I used my KME and finished with my strop and achieved a hair shaving edge. Later I went for a walk and came back to this video on my feed. This video is over a year old and I'm sure it's no coincidence. What strange times we live in.

I just bought the Kadet Pro thanks to this video, Felix! Also added the 2000-3000 grit Arkansas stone.

Felix, you've found a new way for me to shave off annoying houseflies. Thank you. Brilliant as always. ;)

Wow, it got really sharp. In my case, the use of the blades is exclusively urban (I go fishing once a year in the Brazilian Pantanal), and I only use a leather strope to keep sharpening. Thanks for the tips and the nice class Felix! Best!!!

This is what it looks like to be committed to excellence. Superb, my friend. See you soon!

Ottimo Felix! Un grande saluto dall'italia del sud! Buona Vita!

I bought both of your two books a few days ago. I hope they will show me some survival advice for the woods and be able to have some fun with projects. I use a DMT sharpener and keep my sak knives sharp. May you have much happiness, wealth and good health in the future.

Dear Felix, thanks for the tips, I always learn something new! Keep up your enthusiasm and stay young!

WoW, Amazing Felix, Have a wonderful holiday my friend!

Would be interesting to see how long will the knife retain such sharp edge. For example, would it still be able to cut hair after slicing some wood few times or would that be enough to already deteriorate the edge.

That micro-view is outstanding! Wow!

Bravo Felix! You did it!

Super technical video! Thanks a lot for all that info. 👍 cheers!

Damn,now that's a very thorough vid with proof that those sharpeners work better than anything else I've seen to date,thanks for this vid,I know what sharpening system I need now , because it doesn't damage the knives and I have some expensive knives and I've always been hesitant about sharpening them simply because I was afraid of damaging the blade too much,I'm serious about that,,,thanks for this vid man really....

Cool video! That edge under the microscope was beautiful. Thanks for the eraser tip for cleaning stones, I will definitely give it a try. I've always enjoyed sharpening a Victorinox as they can be given a great edge quickly and with simple tools. Often on woodworking blades I use Mother's Mag and Aluminum Polish on a piece of thin cardboard that cereal boxes and other food items are packaged in. It gives a wonderful polished scratch free edge. I also use the old woodworkers method stropping the edge across the palm of the hand to maintain an edge or hone the edge. It is leather after all.

Your sharpening videos are fantastic! thank you for adding to my knowledge toolbox.

Great tips as always, my friend! Thanks a lot for sharing your knowledge with us. Hugs from Brazil!

Excellent demonstration showing the importance of sharpening an edge precisely using exact and equal ground angles. 🎁🎄🔎

Moin Felix, es geht doch nichts über ein richtig scharfes Messer! 😀 Stay sharp und ich wünsche dir und deinen Lieben ein frohes Fest. Peace Stephan :-)

Felix, I am most impressed. Well done, sir!

Hello from British Columbia 🇨🇦

I'm using same Swiss knife since 23 years. I'm amazed of scissors. I did cut everything and still sharp. I love to use when im on fishing.

I wouldn't have thought it possible if I hadn't seen it. Great work! 👍

Wow! That’s sharp!

That is seriously sharp! Thank you for the awesome content you put out. The secret is the stropping. My latest Spartan showed a BESS-score of 165 out of the box. After 5min of stropping I got it down to 85 and it was hair splitting sharp. The chisel grind on some knives are even easier because of the more acute sharpening angle. Stropped a brand new Skipper for a few minutes while watching this video, tested the knife and got the score 75. I usually maintain the blades just by stropping and if sharpening is needed I use Spyderco ceramic rods, freehand. They are super hard/fine grit and the set has 4 different shaped rods so you can do the serrations, too.

Great video!!! Thanks!

Süper good video. Very exciting. Thaks man. 🤘🐺

A very sharp instruction ! Thank you

wieder mal gut gemacht!!!!

Felix, you continue to impress. I wish you and your family a very Merry Christmas and a safe and Happy New Year!

interesting - experimenting and patience 👍👍

Brilliant! Another fantastic video Felix.

Thanks for the effort :)

Speechless

Super interessantes Video, danke!

That’s a SHARP blade! Good job brother 👍🏼 I usually just use a strop and I started with the “2 penny jig”. Just 2 pennies glued together to give me the angle to strop at. AWSOME video as always!

Excellent. Thank you.

Excellent.

The old intro theme! I love it

No one has these tools. Just do your best. But the info on steel is very good.

Ha ersch vor churzem di Kanal entdeckt Felix. I schäme mi fasch chli für die Bildigslücke. Du bisch sone ufgtellte Kerli. Macht freud dini Videos zluege u stolz weme d"Resonanz us de Kommentär liest. Alles guete zum neue u mach so witer. Gruess Bärni

Fascinating viewing and a very different look at blade sharpening than I have ever before seen!

Wow! That is super sharp. Love and blessings!

Cool, very good job. I love your video.

Now that's the definition of "scary sharp"

Impressive. Thanks!

incredible, amazing, i've never seen anything like that before

Really amazing Felix!!!

Wonderful Video Felix, your knowledge is is greatly appreciated. Happy Holidays to you and your family.

As usual very interesting and enjoyable, 🙏🏼

That was simply amazing Felix. Now that is a sharp knife brother.

Brother, I am just proud that you get paid to do this! Carry on!

I need to get a sharpener like that! What a great tutorial on how to get a razor sharp edge! Thanks again for another great video! Wishing you and your family a very Merry Christmas!

Amazing work, Felix. I've noticed similar results going from stones to sand paper as well.

Great video!

That's amazing! Congratulations on an amazing edge.

Awesome. Good job, Felix.

super video! Habe per zufall deine videos entdeckt...hatte davor keine taschenmesser, mittlerweile ist es zum hobby geworden! liebe grüsse aus der ostschweiz, mach weiter so!

Felix , good video , thanks for sharing , God bless !

excellent video thanks. at 6.00 till 6.09 you grinding the blade sounded exactly the same as the flying sound effects for the UFO craft in the 70s TV show UFO. Made me chuckle, wonder if anyone else ever notices?

Wow! Outstanding video. Really good info.

A leather strop is the best finisher for a hair-slicing edge. One side with compound, and one side bare, smooth grain side. Screaming sharpness every time, as long as there's no damage on the blade.

Super Cool!

Absolutely great work mate. Love your videos.

I really love sharpening, thanks🙂👍🏻

Absolut genial danke

Very impressive!

Very impressive work Felix! Just amazing

Increíble, saludos desde Costa Rica

Wow, very sharp! Great job! JT

Very nice great job. Now that is sharp. Thanks 😊 🙏

Great videos !!!

I have achieved a hair splinting edge with 440c, using a lansky, finishing with there 1000grit ceremic, yes it's cleaned with a rubber as oil dies remove the metal dust but seems to smooth out the ceramic stone I found. Good job, I chose 18degrees. Enjoyed the microscope shots. 👍 I also found your axe sharpening video to be a great help. Thank you.

Nice video as always!

Dear Felix, thank you for this video - you went into something like deep material science instead of making copy of the basic videos about how to sharpen a knive. That´s why your content is different an worth to watch. You did a great job, again! Greetings to Switzerland, regards: René

Very interesting to see this, I do like a very sharp knife. Your rig means I’m buying one, thanks Felix !

🙆👏👏👏 excelente, un gran abrazo desde Argentina!🇦🇷
