What a Scandi Grind SHOULD be like

Doesn't matter whether it is a mora, a Koster, Helle, or any other number of scandi ground knives, IMO this is the way the edge should be, yet many don't take the time to get them to.

Many other grinds, convex, v-grind, or even a slight convex on a flat grind can easily be taken to a high polish. The scandi is super easy knife to sharpen, however, getting to the same level of polish the first time can take quite a bit of time. The reason is you are in contact with a lot more steel during the sharpening process.

This is a very tough thing to show in pictures, but this is my best attempt.

Here is a picture of the blade in focus. You can see the scratchy finish on the blade.

Now, a LONG distance away there is a reflection in the edge. There is a reflection because it is so highly polished. It was very difficult, but I tried to focus on the reflection, and not the knife.

The only way I know to get that kind of polish is through elbow grease. If anyone else knows another way, please let me know. This is pretty time consuming, and I took this particular knife through the waterstones all the way up to 6000 grit.

I have been doing this with my scandi's for awhile. Ironically, Ray Mears has a video on scandi sharpening with water stones. Even funnier is that my water stones are the identical brand and grits that he uses in the video.

If you want to watch the video, the waterstone part is about halfway through.

This high polish does several things for you.
- It increases durability.
- Extends periods between sharpening.
- You are sure the edge is flat, and therefore the most efficient it can be.
- It is much sharper!

It is hard to explain, but for a given angle, the knife will be much sharper. The particular knife in the photo is ground 25 degrees inclusive, because that is a classic "woodworking" angle. For that reason, that is why it is popular with bushcrafters. Woodworking. Still, 25 degrees is durable enough to handle batoning, carving and other stuff that can be tough on the edge. Yet, most carbons can be thinned even more and hold up. Yet at 25 degrees, this thing cuts like a much sharper knife.

If you touch it with your finger, you can feel it picking up tiny pieces of skin :D Just the way I like it.

This post it note doesn't do it justice, but if you can do it, the knife can make the tiniest hair fine curls.

Please note, this has nothing to do with the particular knife used. I am just trying to show a way to maintain a scandi edge in a way that most people don't.

Once you get it set up this way, the majority of your work is done. Maintenance will be a breeze from this point forward.

Any thoughts?

Actually, I didn't intend this to be about "my knives." In fact, I try to finish the edge as smooth as possible, but there is no way I could hand sharpen each one to 6000 grit on waterstones :D

I just wanted it to be about the process of doing it yourself to ANY scandi knife.
 
Wow, that thing looks sharp..... and pretty too!

I have been thinking of picking up those waterstones for awhile, but I never had many scandi's to make it woth the expense. Now that I have a few, one being your's, do you feel it is worth the expense? Also can you pm me where you got your stones?

Thanks
 
You have done an great job from the looks of the pics, and I have experienced your excellent sharpening skills on a Koster some time back. I know this wasn't intended to be about your knives, but I still have to get one someday.:p;):D:thumbup:
 
those stones look really useful. i need to pick some up at some point, as i am currently operating on one medium arkansas stone. i like the way stones sharpen as oppose to sandpaper and things. also, do you strop your scadis? i have been debating whether or not i should strop mine, since over time it seems like this might convex the scandi.
 
I totally agree Brian, any edge is best when highly refined (polished).

The fact that a true Scandi grind takes more work then most to reach this level of perfection means that many people have trouble getting them looking as good as yours.

PS – Great photos, showing the reflection in the polished edge speaks volumes.

Brian,

This depends on the steel. Good friggen luck getting S30V to that kind of polish. I can get close - but nothing like 01.

I agree though - it makes for a GREAT edge.

Great work on that edge.

You can use the bevels as a signaling device. :D

also, the shinier the edeg the les resistance that is felt as you cut, for carving a shiny edge leaves a shinier finsih on the wood.
 
also, do you strop your scadis? i have been debating whether or not i should strop mine, since over time it seems like this might convex the scandi.

Yes, I do. Once you have been through this process, you begin to realize just how little a 1200 grit stone is actually removing. Not to mention a 6000 grit stone, and even less material being removed with just plain old leather.

If you round off the upper corner of your edge, no biggie. Even if you manage to round the actual edge of your grind with leather (just a bit) it is negligible to what is taking it back through the sharpening process on stones will do for you.

I hope that makes sense :confused:

Works for me anyway.
 
I'll tell ya, I stropped my Jarvenpaa Leuku and puukko a good while back (wood backed strop, so minimal convexing of the edge took place), and I posted about how little force it took to cut right through a leather glove and cut me nearly to the bone.

Great pics.
 
That second pic is a winner. It shows how much time and effort you put into that edge.

My Koster Bushcraft in 3V is a tough one though. I've got diamond stones for them and hope to approach the shine you got. It's just making the time to do it right from the get go.
 
Damn Brian I just wiped a smudge off my monitor and cut my dang finger on your knife, dull it up man before someone else gets hurt !!!!!
 
Wow, that is a sweet looking finish! Looks like a mirror. I guess that is the point of a mirror finish.
 
That is easily the most beautiful scandi edge I have ever seen. :eek:
