Every time I see your modifications for your SAK, it makes me wonder why Victorinox didn't think of that when when they designed the knife.

FYI :- The actual thumb stud is available (in many styles) from any knife making supply store and even some knife dealers will stock various thumb studs. Some of these thumb studs are threaded for "screw in" the blade where the hole in the blade must be tapped & threaded, and other models that are "screw together" types that do not require threading, but rather are two part and just use a hole and the two parts screw together. Using pre-manufactured thumb studs does make this adding of a one hand opener much easier. P.S. If you do happen to cut into the hollow section of the plastic handle, a drop of clear epoxy can fill the tiny void and a bit of polishing will smooth out the opening.

Good idea in case you really need it. Whenever I cut a bolt down, I thread the nut on first and twist it down to the head. It makes smaller bolts fit into your drill straighter, if that's necessary. But the main benefit is that when you remove the nut it cleans up your threads where you made the cut. I think a drop of removable Loctite on the threads before final assembly might not be a bad idea.

Felix, you are the most clever guy I have ever seen!

Mr.Felix you truly are a gift to KZfaq my friend! Always awesome to see you doing something epic! And the how to makes it 100% better! I thank you so much for sharing your thoughts, knowledge and time with us! Hope you and yours have an amazing weekend full of blessings bruv! Cheers, Kimmers and Jerbs 👍🏼🇨🇭🔥🔪🔥🇨🇦👍🏼

Nice modification Felix , thanks for sharing , God bless !

You never fail your fans...with this vid, we remain devoted!

Felix, alter Fuchs, da hast du ja wieder etwas ausgetüftelt!! KLASSE!! Danke!!

Mehr solche Videos Felix....das ist genau was wir alle sehen wollen. Kreative Schweizer Handwerkskunst. Gut gemacht.

great video as usual, and a good modification for the SAK. I would NEVER do this to my Vic's, as this would void my warranty, even though the quality of Victorinox is so good that I don't think I would ever need to use my warranty. I can open my SAK with one hand now (without any add-ons), but it is slower and a little more complicated. I learn to open ALL my folders with one hand ever since I watched 127 Hours, because you never know when you will have only one hand that you can use to open your knife (even more times than if you have a boulder catch one hand), and I usually carry a fixed blade as my primary (almost ALL my fixed blades have a sawback, some better quality than others, but I really like my Carnivore-X), and always carry my Swiss Champ (usually anyway) as my backup, and as my primary, if I am NOT carrying my fixed blade. That said, I do have an inexpensive SAK, that I may do this to, just to see how useful it would be.

Wicked, just wicked! Keep thinking, Felix!

Felix Buck knives has a stud for 8 dollars US a great one , you are the best genius !!!

Excellent job. I don’t believe my level of craftsmanship would result in such a professional product as yours !

As a lefty I apreciate so much this Sak modification! I think it could also work in 111mm Sak with slide lock without modifying the scales. It could make my old Work Champ even better.

Well done, Felix!

Superb modification.

Next time...how to switch all the tool in oposite direction to make it work for a right hand person ;-)

Great job Felix, you used very simple parts anyone can find as well as tools and made a great product!

This guy is a victorinox genius. I enjoy these videos immensely.

This guy read my mind. Literally. Just a few days ago I imagined a one-hand classic vic 😆

This looks like an interesting mod, but I’m concerned about the blade being weakened. Maybe silver soldering a piece onto the blade would work better. I have a Swiss Army knife for use while kayaking, including if I end up in the water needing to cut things (e.g. rescue) where one handed action would be useful, but I also want a UK legal carry, i.e. It must not lock. I also have a Leatherman Crunch which I’ve considered modifying the locking blade to make it non-locking. Maybe I’ll spin up the milling machine and sort it one day.

Ja Felix! Sie sind sowohl erfinderisch als auch geschickt.👍 Bei allem Respekt, ich könnte mein Schweizer Taschenmesser nicht so brutal behandeln 😬... Ich werde meine Nägel weiterhin tragen 😊... Ich wünsche Ihnen ein schönes Wochenende!😀

Danke Felix, Nice to see you! t's been a while!

an absolute banger of a mod felix!! great work, as always!! keep it up!!

You are magic ! The reason why I use a leatherman every day instead of a sak is the one hand opening, with this tutorial I know how I can change my SAKs. So simple, so clever ! Why didn’t I think to do that before !

👍👍👍👍👍Very nice work and original idea. I enjoyed your video. Keep up good work!👏👏👏👏👏

Very impressive modification, thank you so much. 👌🤠👍

Ah man, that’s amazing. Very skilled work Felix. I bet there’s a Victorinox engineer or designer watching and saying “why didn’t we think of that?” 😜😂 You never fail to amaze me Felix👍🏻👍🏻

Great mod to an already good tool. Something that may make it go easier: thread a regular nut on the bolt before cutting it off then as you unthread it the nut will work as a thread chaser to clean up threads, making it easier to start your acorn nut when the time comes.

Just discovered your channel. Your videos are GOLD!

I have been requesting for this from such a long time thank you Felix

Excellent!!!!. Un saludo desde España 🇪🇸✨

Best SAK-mod ever!

Awesome, great job, Felix!!!!!! Congratulations. Thanks!

Hi Felix, another well thought out modification for someone needing this, great stuff again. Cheers Will.😊😎

MORE THIS BRO, EPIC!

Felix does it again to bad I didn't have this know how about swiss army knifes when I was a kid fast forward 40 years later. Good music

Hello from Detroit Michigan USA Great video thank you for sharing your knowledge and expertise and for what you

awesome modification Felix

Eres un Crack Félix,oleeeeeee ,un saludo desde España 🇪🇸

Thanks again Felix!

Very slick idea.

Nice job! Thank you for sharing this.

Thanks Felix that will work for Germany too👍❤️😀

lovely work man , truly

Super gemacht & präsentiert jetzt ist auch der Standard Victorinox interessant Danke

Wow! So cool! That's such a neat idea! Thanks for sharing that with us!

Great modification Felix. Thank you

I will certainly try this. I have other pocket folder knives I want to do this . Recently I shined up the scales with some used Swiss army knifes and giving them as gifts thank you

wow that is a great mod! I wish the knives came like this from the factory. SAKs are great but a one-handed knife deploy would make it even better

Brilliant.Wish I could put a dozen likes. Cheers

Nice modification Felix! Another option might be the Thumb Stud for Buck 110/112. This thumb stud requires zero modification to the blade. It fits over the spine of the blade and uses a set screw to hold it in place. It can be placed wherever it works best for the user. Ambidextrous. Can easily be removed with no marks or damage to the blade. The handle of the Buck knife does not need to be modified either, due to the height of the blade spine above the handle scales. The SAK handle might need to be modified. Also, the t.s. I am referring to only fits a certain blade thickness range. One would need to verify the thickness of the SAK blade BEFORE ordering that part. It runs around $6-$11USD depending which website it is purchased from. Thanks Felix!!

Genau so ein Messer habe ich mal einer alten Hausfrau auf einem Flohmarkt abgekauft. Sie sagte mir, "2 Euro müsste sie für das Spielzeug schon haben." Habe ich ihr sofort in die Hand gedrückt mit den Worten, "DAS ist kein Spielzeug..."

what a good MOD. my friend!!!!!

The Tony Stark of SAKs right here folks. Brilliant

Great modification Felix ! Left handed people must be so happy rn !! LoL The music though 😖urrrgh

This is pretty impressive! Well done, man. Love your channel! Subscribed!

You’re an original, Felix. I love it.

Wow, fantastic Felix, really cool.

Awesome. Nice modification. I like they way you use what is commonly available to make what you want. I enjoyed the first song too 😉

Klasse gemacht...vielen dank für deine arbeit und die gute unterhaltung

😍😍😍 Wunderbar und fabelhaft, herr Immler! That makes so much difference! I bought an old blunt SAK to practice modifications, before I ruin my Champ or Outrider... This video I will watch mor often before I try. Great teacher, you, as always.

Your videos soothe an aching mind, brother. ❤

Great video Felix - never thought of that. NICE!!!! Best Gray

Very nice modification Felix, hand made makes it unique 👍👍👍

Wow ! Thats fantastic 👏

EPIC MOD! Well done as usual

Very nice workmanship! 😎👍🏻

Another well done video brother!

Excellent idea. Great job!👍👍

Awesome idea and great work.

Felix did it again! I love these companies that warns about voiding the warranty while, secretly, enjoys the fact the is a community that continuously buy their products for customizations. Just see Seiko for instance.

Good Friday to you Felix. Very cool mod. Thanks for the inspiration and sharing your knowledge.

Ein Einhandöffner für das Victorinox - eine tolle Idee!👍👍👍Liebe Grüße aus Oberösterreich!

This is exactly what I was missing. Great again...

That's pretty frickin' rad.

Wow, das ist super cool mein Freund Felix! 💪🏼 Ein toller Mod! Endlich keine Probleme mehr nach geschnittenen Fingernägel 😁 Glück auf us Züri! 👋

Super clever. Love the use of drill & grinder together. But a serious Mod.

Very cool. I love the innovation 💡

Good work, thank you.

very clever idea

Very cool! I just recently thought of doing that with my Opinel.

Muy buen trabajo, y queda prolijo y es práctico, tendría Victorinox aplicarlo en sus modelos, incluso en las de 111 mm. De nuevo te felicito, y saludos desde 🇦🇷
