Edge Geometry Discussion

Most of my knifes are either convex or scandi. Some end up a kind of hybrid scandi-vex over time.

What is your preferred edge geometry and why?

 

Scandi. They are the easiest (for me)to maintain even if all you have is a chunk of sandstone. Also as I have Moras everywhere and that grind just works for me.

 

Tanto that way it will go thru the soft armor and a car door if needed strong sharp and pointy
I'm more of a carbon steel guy that way I can sharpen with a rock if needed though not recommended

 

Carbon steel here, too. I like a full blade edge as opposed to an edge that only goes partway up the blade. I also prefer a full size tang.

 

I told a half truth I also love my MK1 Trench Knife

 

Depends on the knife's purpose. Sometimes convex is best, sometimes a hollow grind is best. I have only recently acquired a few Mora knives, so have little experience with the Scandi edge.
Choice is always a good thing.

 

I have several knives with different grinds ,all have their purpose.
The man with the edge, is the one that can work with what he's got, even better with a broader selection.
I was actually thinking of making a knife with two different sides, a combination of edges .

 

For knives (as vs. other cutting tools such as axes or machetes) all of mine start with either scandi or hollow ground. Invariably, after time, use, and sharpening, they wind up with a compound configuration. I don't have any particular preference as long as the steel holds an edge. Whatever that stuff that Bear starts with is, then heat treats, works just fine.

 

Convex on my larger blades, V on the smaller generally but they also sometimes get a convex edge.

 

Convex for most of my blades, as it the easiest hand finish I can get with out using a blade guide! What ever factory edge I get, I end up convex sooner then later. I find I get good edge life this way, and while not as sharp as the other types like hollow ground, they do seem to stay sharp longer!

 

If it comes to processing wood a scandi grind is appropriate as it will take the abuse of battoning and splitting the fibers carving the wood abrubtly and generally holding an edge for that work very well, generally speaking.
A hollow grind though it separates wood fibres well is rough work on the thin hollow and knots with in the wood are often unkind to hollow edges ,not a knife I'd want to be battoning, but a knife I'd prefer to do my butchering .
The convex edge is a compromise between the two, IMO giving a strong edge that holds up well with abuse and maintains a good edge skinning.
Many of my early knives I made convex on the leading edge and hollow after the belly .
I generally do not batton my knives, preferring to use an ax when necessary .

 

Must admit I'm partial to the saber grind and a full tang on my field knives.

But the topic was edge geometry, and you decided to overlook all the bits & pieces that were offered related to the topic at hand. ??

 

You opened the door. Ref your post #13.

 

Judging a book by it's cover are you???????
Blade Grinds, shapes, etc etc..... Selective reading???? .... I may have opened a door, but I believe you were the one that selected not to take advantage of all the information available. JMHO.

 

You're new here so you may at some point get used to the idea that thread drift is a specialty of the house. Mods usually don't get interested in thread drift unless it goes WAY off the rails. That does happen when someone doesn't let it die. I'm done, carry on if you think it's worth getting in a last word.

 

Is that what some forums call baiting?
I'm new, but I wasn't born yesterday!
You have been called and you are screaming for Mod assistance, but I stuck with and added to the original agenda.
So you have the last word, but it is inconsequential.
I bow to your all powerful eminence Merkun.

 

My interweb searches about forging brought me to this site about a year and a half ago. One member was striking to me. I stayed, and many more stood out. But....

@Hanzo , I believe you need to lure/goad/bribe/coerce our iron monkey @Bear to weight in on this topic.

As a suggestion, lure him with one of those fine suppers you seem to enjoy/flaunt so much!
