A better absolute sharp edge than INFI?

pardon me, I meant that the saying about D2 "It takes a lousy edge and holds it forever" is wrong, proved by your post.

I went on to say that edge geometry is important.

That is my lamp you see reflected in the blade. 60k grit paper seems to impart a nice polish... lol

ok, you were being facetious?

yes edge geometry is certainly important, but all things being equal, i have found d2 to take a sharper edge.

I just meant to say that, compared to nothing, INFI would be better thin.

I have always admired Bill's knife designs and workmanship.. and that one is a beauty.

I think a lot of it has to do with blade geometry... and to answer your question... the sharpest edge I have achieved on ANY knife was on my modified CGBATAC.

The blade profile is quite different to the standard model and the edge is much thinner, but, it is still tough enough for batoning through hardwoods.

Yes, there are two factors that determine the sharpness

1) Edge geometry, it determines the initial sharpness
2) Steel, it determines how well it holds the edge. It also determines how thin the edge you can make. Some steels has larger carbide matrix than others, the smaller the thiner edge can be achieved.

In general Busse has thicker edge profile than others to be heavy users. So it will be apple and orange to begin the comparison with out considering edge geometry/profile unless you reprofile the edge to be the same and test.

However, on the edge holding, the test so far I believe INFI is the best.
 
I've never seen a knife as sharp as the edge Charles May puts on his knives in D2 or s30v.

I think he could use any good steal and it wouldn't mater a bit on the initial edge.

What would mater would be the characteristic of the steel. Some will stay sharper longer, others less chip resistence, but INFI seems to be the best of all worlds.

SO I have spent most of today refineing edges of knives with this INSANE 60,000 grit sandpaper I got from HandAmerican.com

I have 7 different knives on the bench and until the last one in my opinion INFI took the SHARPEST edge.

But I just did one of Bill Buxtons forged 52100 knives and I think it is sharper than the INFI. By that I mean that it takes a edge that is finer and sharper.
:eek:

This Buxton 52100 is some fine grained easy to polish sharp stuff man.

I bet INFI will hold the edge longer especially for hard use but damn......Woot this little knife is sharp... Not even sure how to test it to quantify how sharp it is.
:eek:

Has anyone else found a blade steel that will take a sharper edge than INFI? Seriously until about 10 mins ago I thought INFI was top dog.

actually, what you are experiencing is quite normal. 52100 (as well as swamp rats SR101) is a super fine grain steel that is famous for taking a fierce edge. I have had many custom knives made from 52100 over the years and they have always been scary sharp. There is no surprise there. However, my busses always seem to stay moderately sharp forever when everything else dulls.
 
Thanks guys for a bunch of koolaid drinkers you handled this post pretty well. :D

I still think INFI is the best knife steel. I was just pretty amazed at the way the Buxton took a edge.

+1 That is a scary edge Soup!

Edge Geometry has everything to do with sharpness. Grain structure and size may also play a slight role when comparing good steels.

If you were to take Swamp Warden (SR101/52100) and a Game Warden (INFI) and put identical thin edges on them.... I would bet that they would cut nearly the same. Technically, the steel with the finer grain structure will take a finer edge. Normal folks like myself would not be able to tell the difference in sharpness.

Now put a thick edge on a GW (INFI) and a thin edge on a Swamp Warden (52100).... The difference now is night and day. The thin edge SW will cut circles around the GW and seemingly appear many times sharper.

The Murray Carter's appear to have super thin and zero edges. That is probably why most folks who own them say that they are sharpest of the bunch.

I have seen and handled quite a few Buxton's from Justabuyer. They all have superb edges on them. All of his knives are highly optimized cutters.

BTW Jim, Beautiful edge work on that Buxton. :thumbup::thumbup:

I'm right here. :D

What? Is some knucklehead trying to split an atom again?? :confused:

I keep telling them -- 'Use a neutron howitzer, not a knife,' I say. And they just keep ignoring me.

At least put on those leader underalls I recommended. ;)
 
Justabuyer is the MAN for putting an edge on a knife, that in undisputible. The fellow hogs in this post are an absolute wealth of information and a kick to talk to as well.....but is it just me, or did someone at the end of the first page imply that there's 102 cents in a dollar now? Haha :p

We don't all ignore you... It's just that I broke my neutron howitzer trying to split my FFBM. :(
