How to sharpen a knife with scandi grind - Casström

[@HandyHomeowner]

I'm watching what you're doing but keep getting distracted by the breathtaking background. Now I am researching Casstrom products to buy...because I love this video so much!

[@CasstromSweden]

Wow thank you! Yes, we live in beautiful place for sure! This is shot in what is called "Gammplatsen" literally translated "the old place" and place where the towns first settlements were and which eaven has stone age findings.

[@rapryan5879]

i just learned how to sharpen a scandi grind without making it look ugly thank you

[@CasstromSweden]

That sort of comment warms the heart! We're glad if we could assist in some small way - makes it worthwhile! 😃

[@K1To749]

For the knives that i use for carving after setting the bevel to zero on a stone i pull them a few times through the ceramic section of a pull through plastic sharpener , this way I don't erode the vulnerable soft steel on the cheeks excessively with stropping and everytime i get a razor edge to work with wood which seems quite ok and strong , only the ceramic part and only a few light passes every half an hour in carving i do that and i quit stropping all together.There is no micro bevel as well or maybe a micron level one.

[@CasstromSweden]

Sounds like you found a good way for your needs. Thanks for sharing.

[@Flushdraw-lw1gk]

I own the Lars Falt. The finest wilderness knife I've ever owned, and I'm a knife buff. Thanks!

Mineral oil works well for protection and is food safe.

[@robertleach230]

That's what I use

[@bossmodus5020]

Ballistol 😉

[@chuckaluck123]

I like your approach. Simple. Thank you

[@CasstromSweden]

Thanks for watching the video!

[@ReasonAboveEverything]

People freaking out about the microbevel. If you want that flat bevel back just spend 30min on a rough stone. Whats the big deal? You modify the edge to your needs. Almost half of the vintage puukos I have handled have had a convex edge or distinctive microbevel for the simple reason that whoever used that knife needed that kind of grind.

[@CasstromSweden]

Indeed. Most of the old Puukkos have a lower angle primary bevel and for this reason needs the secondary bevel. A seconday like this could take 30 minutes to remove but I would not reccommend it. The typical Scandi Bushcraft knife we make has a bevel angle of around 15 dps and a tiny microbevel is all that is needed. This only takes a couple of minutes to remove so it is unclear what people are getting upset about. My guess is that they didn't really watch the video.

[@Wastelander13]

I think most people complaining about the micro bevel dont even know what the are talking about but do so because they heard it on youtube. 95% of youtube clips are just crap but people make their opinions with that.

[@bossmodus5020]

Real Puukkos or historical knives always have a convex cutting edge! The real Skandi is a Skandivex😉 if the knife is regularly sharpened by hand, a Skandivex will automatically develop over time.

[@grumpytrumpy8015]

Thanks for this informative video, could clove oil possibly be used also as a preventative.

[@CasstromSweden]

Never tried it. Most oils wil protect a blade, but the main issue is to see what happens over time in different conditions. Maybe read up on it and find out how well it lasts when in contact with air or just test it out. If you are unsure of how foodsafe it is it is probably best to clean it off before use with food in any case.

[@nealeware9163]

Thank you for your video. I was just wondering tho that if you used Olive oil on you blade what would it do to your leather sheath over time? Have you ever used beeswax?

[@CasstromSweden]

So the olive oil must be used in moderation on the blade like any oil or rust protector to avoid it building up over time in your sheath. If you live in a humid area the best thing is to store the knife and sheath separately when not used. Beeswax mixed with olive oil would work, but beeswax on its own would be too hard. You can also use our Lapland Leather Wax which works well.

[@nealeware9163]

@@CasstromSweden I have used Beeswax on my saw blades and on one of my knives. You can get it in small blocks and it is easy to rub on. You can also just heat your blade up a bit or leave it in the sun for a bit and the Beeswax will just melt onto the blade as you rub the wax along it.

Needs more close up my friend .

[@CasstromSweden]

Yes, Probably :)

[@Macovic]

Spotta på (spit on) a fine natural stone is someting grandpa suggested. He also recommended adding significant amount circular motions to get a very (very very) slight convexing.

[@CasstromSweden]

Yes, that is also a good technique that can be used.

[@georgeyoung4292]

Yes sure😶🤦‍♂️ Maybe for raw iron or mild steel in annealed state but anything over 55hrc witch butter soft for any cutting tool and you can go ahead and rub it for 24hours while you can finish a knife in 5passes on diamond pocket stone... For sharpening steel you need serious stone with novaculite or jnats with silica and alumina grains witch we dont have in Sverige.. Your grandpa is out of his mind vännen😂

Very nice vid! Would you please share the name of the knife you are using in the video??

[@CasstromSweden]

We certainly can 🙂That is the Casström Lars Fält Lock Back - a tough folding knife that's a great little tool for carrying in the pocket!

[@barbar7746]

Hello, thanks for the video, but I have a question: why do you need to sharpen the scandi edge if after that you add a micro secondary bevel? It looks more simple to me just to work on a secondary bevel directly. Also it would be less steel removed than sharpening the entire scandi edge.

[@CasstromSweden]

Thanks for the question. It is possible to sharpen only a secondary bevel, but then it will no longer be a micro bevel and over time it will make the bevel wider and the edge clumsy, reducing the cutting ability of the knife. To retain the best cutting ability the edge should be zero-grind or have a micro-bevel that is as small as possible.

[@barbar7746]

@@CasstromSweden Ok, I can see that. Thank you for this great answer. it will help me sharpening my knives.

[@MrPatrick7777]

That is an excellent question. And an excellent answer. As an American I have much less experience with 0° bevel, or Scandi Grinds, than the secondary bevel blades. I may have a little more experience than the average person here due to wood tool maintenance and the like. The Scandi grinds simplicity and utility-to-mainenance ratio is making it my favorite style of cutting tools.

[@MMWhittemore1]

Thanks. Always a pain to keep an edge on my Helle knives ...

@Ukraineaissance2014 I have a few of the cc4 and dc4 stones in various kits. This one just looked thinner so was interesting

[@P.J.Thompson]

Nice video thanks! Will you ever make a lars falt with bog oak handle?

[@CasstromSweden]

Possibly, but currently no plans. Bog Oak is not a material with unlimited supply either.

[@StevanOutdoor]

Actually free hand sharpening and stropping will convex the edge. That's ok and even makes for a more solid edge.

[@CasstromSweden]

Indeed!

[@tiddybearkush]

Not if you do it correctly. Most people won't put the time into properly free hand so I guess that's how their knives end up.

[@StevanOutdoor]

@@tiddybearkush Nothing is impossible but hand held doesn't make a steady surface to work on. Keeping the scandi means removing relatively a lot of metal so fatigue plays a role. Also a small secondary bevel makes the edge stronger

[@alandeacon1988]

What grade of sharpener do you use. please?

[@CasstromSweden]

600grit

[@alandeacon1988]

@@CasstromSweden Many Thanks!

[@Cool-Lake]

Can you use water on the diamond stone or oil? Can you recommend a good diamond sharpener?

[@CasstromSweden]

It can be used dry or with water or spit. Problem with oil but it makes it more messy. Dianova sharpeners are good.

[@TheWizardOfTheFens]

Are the complaints about microbevel use coming from people with experience (I’m 65 and have been practicing for over 50 years) or just going with something John Doe said on his KZbin channel?

[@haytembeddida917]

What is the ideal sharpening level for a Scandi knife? Is 1000 degrees enough?

[@CasstromSweden]

I think you mean 1000 grit? Yes, it is usually enough to make a very good edge. However, be aware that there are different grit scales used by different manufacturers and some products that claim to be 1000 grit is in fact much more coarse. So test and see.

[@kotyzaano3082]

Jag skulle vilja ha exakt typ av kvarn, tack.

[@CasstromSweden]

Kvarn?

[@peetsnort]

I make sure the diamond plate is always wet with water

[@whiteyfisk9769]

Wash it after, but working with it wet will make your plate gunk up with metal shavings

[@freenational]

What grit stone to use?

[@CasstromSweden]

600 grit is quite an allround grade.

[@Revelation_Overland]

Just bought the Casstrom Lars Falt. Beautiful knife, however my first day out with it I was cutting off a patch of feathered stick and smacked a close by rock and put little chips in the belly. Pretty upset about that.

[@CasstromSweden]

Man, that's sad to hear. Hopefully you can take the chips out with a bit of sharpening. Good luck!

[@SuperM1man]

Just so you guys know we don't know what a centimeter is, is that like close to a quarter inch? Or one eighth

[@CasstromSweden]

Google excels at these types of questions. They suggest approx. 0.392 inches. I would make that 2/5 of an inch right? :)

[@Van_Nop]

yeah a lot of us do, as well as inches ar mentioned we need to convert

[@Ukraineaissance2014]

1inch is 2.5cms. Use cms/mms its so much easier.

[@Robert.Northwoods]

It makes more sense to sharpen knives in longer strokes instead of ruining the geometry with what is shown in this video. And yes I‘m using a DC3 or 4 even on 16cm blades.

[@CasstromSweden]

Different people have different techniques and whatever works for you is great. 👍

[@glodandorin7807]

Super video.

[@CasstromSweden]

Thank you!

[@BobanMisevic]

1 When you have smaller stone like yours, you take stone to the knife not other way around 2 Entire point of scandi grind is not to have second bevel

[@CasstromSweden]

Hi Boban! Thanks for commenting. 1. We find this way is effective, but of course, it is what works best for each individual that counts. There is nothing set in stone, excuse the pun! :) 2. It's not a second bevel, but a micro bevel that we recommend (if you are going to be using the knife to split wood). Thanks for watching!

[@littlewoody5539]

Butter butt oil works the best .

[@CasstromSweden]

😂Not heard of that one.

[@johndemeen5575]

Good way to cut your thumb, not too bright. From St.Paul,M.

[@CasstromSweden]

It can feel strange and unsafe in the beginning, but with this size pocket sharpener, it is effective and safe when you have practiced it and have the correct skills. If you feel uncomfortable doing it this way the sharpener can be brought to the knife instead. The sharpener can also be secured flat on piece of wood and holding the knife with two hands. The important thing is to follow the scandi grind and re-sharpen the entire bevel.

[@Catastrofius]

Micro beveling a scandi is NOT the way to sharpen a knife. You end up rounding the edge. Poor advice my friend.

[@CasstromSweden]

Hi there! It all depends on the angle of the grind and what the knife will be used for. But this is the way we find works best for durability for most areas of use with a grind angle between 13-15 dps.

[@warwickshireoutdoors]

Very nice. I have the No10 and folding knife and love them both. ATB🏕
