Scandi grind on a new puukko

[baggins]

Hi folks, i've just bought myself a new iisakki Jarvenpaa puukko. I have had a stainless steel bladed one for 15 years and took the secondary bevel off it to make a true scandi grind, and it has always been great. My new one is carbon steel, and it comes with a secondary bevel on it already. is it better to leave it as is, or remove it? It will be mainly used as an all round blade; ie, food prep, wood carving etc. (not much game prep, and i don't use my knives for battoning).
i jus wondered as i know carbon is harder than ss and a little more prone to chipping.

I'd suggest zero grind scandi is a specialised wood working tool,
due to the angle of 'attack' when carving.

A small secondary bevel is stronger (more metal behind the edge) & more suited to all-round use.

A lot depends on the heat treat, thickness of blade, and angle of primary bevel,
so there is no definitive answer.

Keeping, or creating a secondary bevel will make sharpening easier in the future.

The angle is larger, so you will perceive the blade as less sharp, but as noted above, it will last longer, and be stronger.

The blade will also last longer, if you sharpen your knife often.

The modern fad with thick blades gives a large angle of the edge already with a Scsndi grind, and to make a secondary bevel increases this angle, which is a negative ( for me at least)

Btw, which knife model did you buy?

Thanks for the replies guys.
Janne, as i already had a Jatkanvuolu in stainless, i decided to go with the original styles Vuolu. I like the simple style and clean lines of it. I was really tempted with the Game knife, but really wanted a carbon blade.

Nice choice, a classic shape.
I love carbon steel knives myself.
To be truthful, there is not much extra care needed to keep them in decent, almost rust free shape.

Me to. The Jatkanvuolu was my first ever (proper) bush knife, but, since then i've always prefered carbon. I've toyed with loads of different designs, but kept finding myself going back to my first one, much to the consternation of my good lady, who i gifted it to.
Already started having a play with it, and it fits in my hand like a natural extension.

Btw, jatkanvuolu means lynx in english.

I have checked out the manufacturers site, and like what I see!

The ‘dressy’ knive styles are very much a Finnish and Karelian design.

Knives like that were worn with the celebration occasion dress.
( not sure the english name or expression).

Your knife was a ‘working knife’.

No doubt your knife is of a higher quality than the more famous Marttiini knives!

Google Järvenpää, interesting!

From what i could find out, Jarvenpaa were THE Finnish knife makers in he 20th century. I do like their designs, but i know they no longer make their own blades. But my older one has been well used and still looks new (even after my good lady left it under my car and i drove over it and only fould it 2 days latter ).
Here's a vid i found of a guy restoring an old one.

Yes, I read today onlinr that they were one of the suppliers to Imperial Russian armed forces!

I think Janne Marttiini started decades later, in an area not well supplied, he saw a good business opportunity I imagine.

Modern designs might be strong, have fantastic steels and so on, but a knife like those are all you need.
Generations of guys have fine tuned the design over centuries, all over Finno Scandinavia.

Even the famous bushcrafter Polack-Canadian Mors Kochinski loved this blade design.
