Edge Profiles (not types)

[Boggs]

At least these are terms I understand......

Sooo...
1) VERY low saber
2) Mid/nominal saber
3) High saber / full-grind
4) Full Flat Grind.

And understand these better than the OP's made up terms......

1) Ol' Betsy grind
2) Tango whiskey grind
3) Banana puddin' grind
4) Extreme inverse hollow grind

Sorry about that.
Terminology is always a hard one...

Your first problem is "edge profiles." "Edge profile" is made up terminology for what is called a "primary grind." You are showing 4 different types of primary grinds. Not edge profiles.

Those terms I understand immediately. But I'm going to run my own terms up the flagpole and see who salutes:

1) Ol' Betsy grind
2) Tango whiskey grind
3) Banana puddin' grind
4) Extreme inverse hollow grind

Work for anybody?

Those I understand. I had to pay extra for the Ol' Betsy grind plenty of times.

Interesting that you think I made up the terms I used. These are the terms used amongst all of my knife maker and bladesmith friends... I only see the terms above in common usage here on BF...
I prefer to stay away from these terms because they carry implications of grind types not just profile... when i hear saber i think underground with a flat grind. But it might be hollow or convex... same with "full flat grind" but it could be full ground convex or even a very shallow hollow grind...

For consumer purposes I guess these terms are fine but for maker purposes there are too many assumptions

You are correct sir. I am talking about the primary grind profile... but not the primary grind type...

So I avoided this term which I think would.have been no less confusing than just saying edge profile...

I hate to say it but you are reinventing terms that already exist. But, every knifemaker has slightly different terms. A good thing is if you describe everything on your website. Then the communication with a customer for a custom knife is going to be much better.

OK, Again, not terms I made up...

Took a little looking but here is a perfect example of terms in use by makers... Fom Jay Fishers site:


think I'm going to just shut this one down as it is giong nowhere.... thanks to those that were actually trying to be helpful.

May i ask WHY you think "flat" in reference to a saber-grind? It is a matter of grind-height, not convex/flat/concave. Most Buck knives (extremely common for knife-users) are saber with a hollow primary and a flat edge-bevel It sounds like the problem is your "too many assumptions" hence the confusion you are causing. Just use the appropriate term and don't "assume" other things about them. Your notion of over/under-ground is contingent on spine-thickness AND blade-width. Your #2 & 3 "under-ground" would be WAY "over-ground" on a normal scalpel or utility blade, and by your definition every chef's knife and many a paring knife and fillet knife with optimal geometry would be considered "over-ground". Do you see the problem?? Your terms are just wrong without reference to specific dimensions (blade thickness, width) and intended use (outdoor, tactical, kitchen, utility, hard/light, etc.)

You asked, we answered, I hope the help is appreciated.

Also, it's your thread so you have the power to close it yourself.

You are right that making an assumption is my own mistake...
However I also assume that if I make a certain assumption others may make the same... knowing this I avoid terms which carry assumptions for some...

Saying i am wrong is just petulent... I may have used different terms than you would but this does not make me, Jay Fisher, or all of my friends wrong it means that we are influenced by different sources and our terms for the same thing vary.

The original point of this topic was if people thought that my descriptions of each grind profile and there functions was right and what they prefer and why to enhance my own understanding of why people choose a specific profile over another...
So no, degenerating the coconversation into an argument over what a grind profile is called is in fact not helpful... it is also reasonable to assume that the discussion is not about scalpels...

But yes I appreciate your help... I did not know I could close a thread on my own.
