What equipment do you guys carry in the field (i.e. woods) to sharpen your Busse's.

Also If I get a full convex edge, that has been recommended for my grovemaster or BAIII, what would you carry. It would be nice to keep a shaving sharp edge in the field.


Would Busse out on a convex edge or whom would you recommend to do the work?

A small rod should be fine for those uses Ed. And yes, I'm sure Jerry would grind you a convex if you asked him and were willing to pay a little more.
 
I always prefer to have a V edges on all of my knives. A convex edge is stronger but even if you chop with your knife a V edge is plenty strong, and it cut *SO* much better. You can control the level of edge durabitlity by how far you pull back the cutting edge. (how much you sharpen). I would recommend a ceramic rod to sharpen a convex edge in the field. Remember when you use a ceramic rod you are almost always putting on a secondary bevel and it can become quite steep, so after several sharpenings with the rod you may loose the ability to regain the edge without using a slack belt grinder or some SIC paper on a flexible backing.:D

My advice if you really want a convex edge use a ceramic rod very lightly to bring back the edge when needed in the field. Otherwise go for the V edge and use either a rod or a small diamond stone in the field. Oh and don't forget INFI leaves a nasty burr so you want to make sure it is totally gone when your done sharpening.:D :p
 
Hmmmm. Convex vs Asym. I can't really compare differences between the two grinds with INFI as I've never owned an INFI blade with a convex. But, my first experience with an asym grind was with my SH1 and that was ATS-34 and I can attest to that blade holding an edge and that edge being more durable than other grinds on ATS-34. In my opinion, there is only a marginal increase in slicing performance with a convex over asym but not enough to offset the other performance factors that I found with the asym grind.

Now, INFI being what it is, is suspect that the durability and edge holding aspects of a convex grind will out-perform everything else out there with a similar grind. And on that basis, I'm sure that the convex grind will serve you well, regardless of your intended use.

BTW, who recommended the convex over the asym and what reasons were given?
 
Spearhead, you get better slicing performance with convex than v?
And a move durable edge with a v grind?:eek:
The convex has more metal right behind the cutting edge, the reason they are usually more durable.:D
 
To clarify, my experience is that a "v" grind slices better but not enough to justify away the other performance factors of an asym grind. Additionally, chopping performance and durability will always be better with an asym than a "v". My point was that given INFI's properties, a "v" grind INFI blade will likely out perform any other steel with a similar grind.

The confusion may be that I was assuming that the convex that Ed was talking about was a symmetrical grind.

Convex edges can be thinner and more acute than flat ground edges, or thicker and more obtuse, depending on the exact curvature used.

In general the advantage of a convex profile is the ability to vary the angle of the edge from the apex to the shoulder to maximize the combination of cutting ability and durability.

The same effect can be achieved to a nearly equal degree with a double beveled v-ground edge. The only thing this lacks is the smooth flow lines of the convex which give the convex edge a slightly lower drag profile.

The disadvantage of convex bevels is that they are not easily sharpening on jigs and such, but double bevels are trivial to maintain in that regard.

Cliff your right, however when I put on my convex edges with my slack belt grinder they are usually pretty obtuse. A very thin convex edge would be very nice. I should try it. Thanks, Jeff:)
