My Lesson in INFI

I recently purchased a used FSH. Not my first Busse or INFI but the first I bought as a user.

It came with the factory edge but used and dull. Not a problem I knew that when I bought it. So I set out to decide how to sharpen this large thick blade.

I have read a lot about INFI and how it stands up to use so I knew going in I was dealing with a super steel. :) So I took the knife and set it up on a edge pro and cleaned up the existing edge. Took about 20 Min's.

Off to the vacant lot and some log chopping. Well the edge of course held up well. But the chopping itself was kinda lack luster. Granted its a new to me knife and I need to learn and practice with it. Still I was not over joyed with Busse love and was just not feeling it!

So I took the knife back inside and thought about it a bit. I broke out the sand paper, sticks, and leather to thin and convex the edge. :eek:

I must say it came out VERY nicely. This maybe to the nicest convex edge I have done and I have done hundreds. I do knives for all my friends and co-workers. From Kitchen knives to "tactical Folders".

INFI is REALLY great to work with. It responds very well to sandpaper. I started out with 100 grit for the relief bevel.(Back Bevel) I took it as far back as I could with out stripping the Blade coating off to far up the blade. Except for the tip. Busse leaves those pretty blunt. I thought about that and left it thicker than the rest of the knife. I am proud of that because it was my first "on purpose" compound edge and the transition is invisible. :D :cool:

I worked through a series of grits until I had a polished smooth slightly thinner convex edge. I stopped at 2000 or 2500 grit I can't remember which and took the knife to the leather strop.

The INFI LOVES leather. I mean the edge came ALIVE on some leather and Chromium Oxide abrasive. STUPID Sharp and Mirror polish.

Back to the Vacant lot and my "test" logs and junk. MUCH better. Bit much deeper into the wood with less binding and sticking. This knife now is much closer to living up to its billing. The new convex edge held up really well and after 20 or 30 Min's of goofing off smacking trees and branches and various old crappy stuff all it took was about 5 Min's on the 2000 grit Sand paper and a quick strop to return it to push cutting news paper sharp.

Interesting knife and INFI really is a great choice. I am sold on MAG handles and any future Busse knives I buy will need to have them. One thing I am not sold on is the coating. Sure gets ugly fast. I am also sure that rough coating does not make the knife slice any better, as it does add friction. I may just satin finish this blade.

Great knife!

Great post!

Keep in mind that the "combat" edge is meant for stupid stuff like hacking loopholes in cinderblock walls that most of us will never encounter, but it is vital for those servicemembers and other public servants who do. Thinning out is relatively easy, but you do lose some versatility, with the compromise being left to the end user.

Good to hear it worked out for you in the end!

This last one shows the smoothing of the coating and seems to show scratches on the edge polish... trust me that is not the case.

Very NICE! :D :thumbup:

I'll give you a little more time with her, she's just beginning to like you, I hate to be a homewrecker, this early into the relationship... :D
 
Nice edge. Keep working the knife, I'm sure you'll change your mind in time.:thumbup:


I seem to have given the impression that I dislike the knife. That is not the case. I like the knife fine, even of my praise is less flowery than some others.

The Expense of this knife convinced to me to really go to town on the edge.
I am a little embarrassed at how much time I have in this. :o
 
I use a 1 inch square stick with a piece of leather glued to it.

Here it is wrapped in sand paper and I use it like a file I push and pull it
over the blade like a file. Takes a bit of practice.

and have you found this works better than stones or steel?

Much faster than stones. Much easier to do convex than stones. More applications than stones. I gave up using steels years ago. Most people think now-a-days steels will re-align a damaged edge but do so at the expense of the entire edge. I guess they may have some limited uses.

I have a wide array of stones and ceramic and diamond tools for putting various types of edges on Various types of blades.

But more and more I find myself turning to sand paper. I think you owe it to yourself to try it.
 
i will, im not real adept at sharpening. i am getting better with the spyderco stones, but your method looks interesting. ill give it a try, thx.

Now this is an edge :eek:! I think you should be giving seminars on your method and how to apply it correctly. Nice job indeed :thumbup:!
