    Hello everybody, I am wondering about different peoples opinions on what blade thickness goes well with a scandi grind. I’m usually a fan of the thicker blades but I’ve heard a scandi performs better with a thinner blade. What do you all think?

    Thin blade no more than 1/8” in my opinion

    My main users are 1/8", but I also have a Varustelka which I think rolls in at 5/32". It's a a mean slicer as well as tank tuff. ;)

    My scandis that are at 1/8” are wonderful. I have one that’s thicker (not sure how thick) and it’s also great. I think it often depends on how high that bevel goes - 1/4” vs 1/2” vs etc - that makes a bigger difference.

    I'm a fan of 1/8" or 3/32" for scandals, but to be fair with the right guy behind the grinder anything is possible. Its all about the geometry of the edge on some knives.

    Like the others have said.

    I like to add that "scandy" is a pretty broad church and a lot depends on the width and angle of the bevels desired, and also on what one expects to cut with the knife. Also, consideration must be given as to whether one wishes to have just a plain primary grind edge or a microbevel.

    For all round usage, I would not go beyond 1/8" blade thickness and the primary grind set to around 23 degrees included, maybe 25. Even so, it will not cut anything other than woods as well as a convex or full flat grind would.

    Something else to consider is the game changing hybrid scandy-full flat grind as found on the Mora Kansbol, which improves the all round usefulness of the knife.

    Cheers
    John

    I found the Jaakaripuukko too thick for a scandi. It cuts like a fat knife with the factory grind. 1/8" or under for me.

    My 110 wasn't a true scandi and it processes wood like a champ. I put a true scandi on the first 50mm of the blade by the handle and that's made it a very nice carver, but I don't know if it actually improved its performance...

    I meant for general bushcrafting, feathersticks, wood processing, maybe even a little food prep

    Anything over a 1/8 is overkill, just my opinion. I like 3/32.

    I have a few, I like to use the thin bladed ones best.
    There is plenty of room for the eighth inch and beyond but the less than the eighth inch feels better, to me, during use.

    It depends.

    If you do more fine carving, a thinner blade is better. Look at a sloyd for example.
    If you're doing more heavy cutting chores, a wider blade will be more robust.

    I believe the more critical dimensions are the angle of bevel (imho about 24 degrees total) and the width of the blade from edge to spine.

    Have fun

    A less obvious advantage of knives sporting scandi grinds is that if one insists on a full tang, the knife can be made lighter than an alternative grind because they require a thicker spine, which translates into a heavier tang.

    One of my favourite knives is a Cold Steel Peacemaker witha 5 1/2" blade, 1/8"thick, and with a hybrid scandi- full flat grind. This is an exceptionally light knife weighing in at 4.86oz, yet it has pretty much a full hidden tang and is strong enough to withstand a lot of harsh bushcraft type use.

    Cheers

    I never thought about it that way, though I question what the best angle is. I'm not a big fan of Scandi grind but whatever the angle/thickness of a Mora Companion seems about right for what I use that knife for...

    I tend to agree that Mora has got it pretty much right. I am not a huge fan of scandis, but must admit that for a budget priced knife, especially if one is conscious about the weight being carried, they are hard to beat. I guess that at the end of the day it is all about compromises....

    3mm or 1/8" feels best without having to get creative (or weird) with grind angles and bevel heights. Granted, my Jakaaripuuko's are 4mm ... but they do not cut as well - I should say, with as minimal effort, as my thinner scandi ground blades. My Bogdan custom, Mora Companion's, etc are much much better cutters because of their blade thicknesses.

    The way my Jaakaripuukko came it was sharp but took many times the effort to do simple tasks because of the fat scandi with a secondary. I convexed the whole thing and I'm never going back. No secondary needed and it cuts much nicer. Not as nice as a thinner higher convex like my BR Aurora.

    I personally like thin blades made of steels that can handle acute angles. My current favorite knife is 0.080, 2mm, thick with a 8dps scandi. My wives favorite knife is 0.060, 1.5mm, thick with a 10dps scandi, she gets very defensive if I start using her knife.

    For crafting in wood and hard use tasks, a thick blade isn't a detriment. As long as the grind angle is thin enough a thick blade will cut, split and feather as good as a thin.

    A thin scandi blade shines when cutting meat, leather, plastic or other slicing tasks. No argument here, .1" or even .07" is what you want for slicing.

    yeah, I'm neither a Scandi nor a Mora fan but I do have a few stainless steel ones scattered about in my beach bag, cooler, tackle box, etc.. they're also my favorite giveaway to friends who have no knife other than something bought in the camping section of Walmart years ago.

    I'm in the minority but I don't consider bushcraft to be all about wood carving or vice-versa. for an outdoors knife I like a full height convex, or a saber-grind if it's thin.

    some folks confuse a saber-grind with a Scandi but to me, a Saber grind is made from thicker stock, has a higher grind, and either a convex or double bevel.

    it doesn't matter much though. I believe you should just pick one and use it till you find something it won't do. by then, you'll know enough to know what you prefer...

    I bet that Jakaaripuuko would cut better with a higher grind/thinner angle. I'd like to find someone to put a full height grind on one and I bet it would transform that knife...

    Thinking the same. It's already a high grind for a scandi (needs to be), but I think it should be higher yet, 75-85% of the way up the blade. Full convex might suit it better as batmanacw did.

    I made one that's 3/16" or so thick. It works but I think 1/8" is probably better.

    A quick google suggests the Woodlore is 5/32". So somewhere around there?

    The grind limits the thickness in that assuming that you maintain the same bevel angle eventually at a certain thickness given the same angle it will simply be a full flat grind. I have a hand forged puukko blade that is like this with the more traditional slightly hollow grind with a micro convex secondary bevel. The primary grind runs very close to the spine as it's a 5mm thick blade.

    Personally I perfer under 1/8 as I find that thickness works best for what we call Scandi grinds.

    That's basically 4mm... same as the Varusteleka Jakaaripuuko blades. I didn't know the Woodies were that thick.. wow.

    5/32” or 4mm is my max for scandi now. I have a knife that is 3/16” with a scandi grind that doesn’t get much use as I prefer thinner. I like thinner than 1/8” as well. I have a few Moras that are probably closer to 3/32”.

    I like thinner knives in general but I like especially thin scandi ground blades.

    1/8" or less is a good thickness for a general purpose knife for me. If I can go a little thinner, I will in a scandi.

    I like scandi ground knives because at the same thickness as a flat ground knife for example, I feel like the scandi ground knife is going to be a more durable blade due to the extra metal left in the blade. And that's why I feel like I can have a thinner scandi blade vs flat ground or whatever else.

    3/32" then 1/8" then 9/64" and that's it for me.
    I don't like them over 9/64"

    Must... convex... Terava 110...

    Great, now I have to snag a mousepad from work and grab some wet or dry sandpaper out of the garage!

    I did the initial grind with a belt sander. You will want to start very coarse and lay the bevel basically flat as you work away the old secondary.

    I like a scandi grind, but I like them fairly high. I'm moving away from the shorter scandi grinds unless they are if super thin stock.

    For me - The higher scandi seems more traditional to me, performs better, and sharpens easier than the shorter (or shallower ?) ones. I have some high grind scandi knives in stock over 5/32 and they still perform well. The thicker stock scandi blades aren't ideal for detailed carving with longer cuts, but works for other tasks.

    Some may consider this a 0 half height flat grind.

    I can tell a pretty significant difference in the cutting forces compared to when I only convexed out the steep factory secondary.

    As it comes, the Jaakaripuukko 110 sucks.

    I want nothing over 3.5mm or 9/64 in a scandi. I have passed on some great knives that were 5/32 scandis.

    For me a scandi is a carving tool and I want it to do that well. I prefer other grinds for an all purpose tool.

    Ive recently purged most of my high end scandis. Ive realised anything over 3/32 makes an average general purpose blade. They just dont slice well. I also like the blade height to be about 5/8. JMHO

    I am glad you mentioned blade height as I feel it's often over looked. As I said I see a scandi as a carving tool and they just dont perform to well on wider blades. Generally I go for a 1 inch max with a few exceptions.

    I say it is all relative. It depends on the thickness of the blade, and height of the scandi grind, which are going to determine the grind angle.

    What I don't care for is a knife with a thick blade and a low scandi grind. The angle is too awkward for most of my purposes.

    The Enzo Trapper has a thickness at the spine of approx 0.144." The Mora Companion HD approx. 0.125." The Mora #2 Classic 0.100." The Mora Companion approx. 0.080." All of them have worked fine for me for what I do.
