Hi all.

Just joined bladeforums but have had my BK2 for a while now. I've been thinking of changing my edge angle to 50 degrees inclusive. Anyone try this yet and if so how is this angle working for you?

Thank you.
 
Welcome.

I keep mine around 40 inclusive, why do you want 50?

Are you worried about chipping or rolling your edge?

I was taking a good look at my blade last night and I noticed a chip on it. I'm not sure what I did to get it. I'm pretty rough with my knives, there tools to me and nothing more, so I may tend to abuse them but not intentionally. So I figured maybe going to 50 would lesson the chances of new chips.
 
I thing that a grater angle will help with edge retention and certainly help reduct the chances of chipping and rolling. But in this situation what does inclusive mean?
 
All of mine work well at 50 degrees inclusive. I find it a good medium for work and edge retention.

Do you notice a significant difference in edge retention over the factory(40, I believe?) angle?

Nope. I do notice that the sheath has the biggest factor in edge retention. For field work, I have never really dulled a knife to where I think it needs to be sharpened to function. It doesn't stay razor sharp after splitting up 200lbs of firewood, but it will swipe cut paper smoothly.

Cool! Thanks for the vocab lesson :D

There are all types of crazy terms for knife sharpening and knife edges.

shoulder, belly, bevel, multi-bevel, convex grind, saber grind, scandi grind, full grind, hollow grind, chisel grind.......i get mixed up every once in a while.

like the BK2 that was modded - full saber-grind convex edge tripped me up for a second.....trying to describe it to someone.

1 Hollow grind
2 Full flat grind
3 Scandi grind
4 Chisel grind
5 saber grind
6 Convex grind

I think this is correct....
 
Thanks Flexxx, and I'm sorry if I started a hijack.:o

No apology necessary.


Story time:
I do okay at sharpening blades, but there was this guy I used to work with at a butcher shop and this guy could shapen a knife, he just had the skill down. what freaked me out was he would test the edge of his knives on his fingernail to see if they were sharp enough.

I tried this once and it gave me a chill up my spine, damn just thinking about it freaks me out...:eek:

Story over, proceed.
 
Thanks everyone for joining in my post and for all information. I went ahead and reprofiled my BK-2 to 50 degrees inclusive and to tell you the truth I can't seem to tell the difference. I went in my backyard today to chop down a dead orange tree (4" diameter) and it fell to my BK-2 with no problems whats so ever. I'll leave it at 50 for a while and keep using it and see how it goes. I can always bring it back to 40 if I want to.

Thanks everyone.

It gets interesting because some of the terms can be used to describe the way the knife blade is ground and some the knife edge....the sharp part.

Scandi grind is a bevel that is usually very tall, used on the Mora and other swedish-style bushcraft knives. That would describe the way the knife is sharpened....you make sure the bevel is flat on your hone and just move it straight across.

You can have a scandi grind -sharpened knife on a saber-grind blade (ESEE-5 with a scandi grind edge). It can get confusing when you don't know whether they are talking about the grind on the blade or sharpening technique.

Just like the huge....uh....BK7 or 9 I think that had a full saber-grind.....it went all of the way up with about 3/4" or so at the top but at the bottom the edge was convexed.

I think your picture is right when you are talking about the grind on the blade itself. Then, you can take some of those types of blade grinds and put different edge grinds on them.

Like the Scandi Knife Grind picture looks like an example of a V-grind sharpening technique.

Also, the Saber Knife Grind is what a multi-beveled V-grind for a knife edge would look like.

The stuff can make my head spin sometimes!

If I was assuming the pics depicted what the cutting edge was called, my immediate reaction, which could totally be off) would be:

1. Hollow
2. Scandi
3. V
4. Chisel
5. Double-bevel (multi-bevel) V
6. Convex

edit:
The ESEE-5 has a saber grind on the blade and could then have the same picture style (multi-bevel) for the cutting edge and they'd both have different names although in theory the angles are the same but just one is at a much smaller level.
