The Warthog company in South Africa has introduced some interesting new
sharpeners - the V-Sharp, and a line of rod-guided sharpeners that
differ mainly in the box they come in. Two of the sharpeners use
diamond hones, a natural for SA, and several feature SA native hardwood
boxes. See my review at http://www.ameritech.net/users/knives/Warthog.htm

It looks like the Warthog hunter would have to be clamped and unclamped to
do the whole blade. I don't get it. You say that it cuts perpendicular but
then how do you move it to do the next portion of the blade?

Have you reviewed or tried these

The Hunter clamp has two degrees of freedom (not counting rotation) so
it moves side to side as well as in and out. So you can cover a long
blade and still cut perpendicular to the edge.

I have invited EZE-Sharp to send a Bladesharpener for evaluation, but
they are not interested. I have made similar sharpeners for really
large blades, so I know the basic idea works. The EdgePro is the same
principle on a more manageable scale. http://www.edgeproinc.com/

Steve for the v-sharp what is the maximum knife thickness which will fit
inthe sharpener. Did you notice and difference in the tendancy to produce a
burred or wire edge compared to similar srock sticks. In theory the v-sharp
should be superior as it hits both sides of the edge at the same time, but I
would wonder how significant of an advatnage this is in use.

Along those lines how much more functional would you rate this for a novice
than a simple set of crock sticks. Did you try it with some very soft and
hard steels (45-65 HRC), as I have noticed that you need to vary your
applied pressure quite a lot over this range to produce optimal results and
I would wonder how well the preset force on the v-sharp would function.

The next group of sharpeners look very nice, it is hard to understand the
function from the picture but can you get an even edge angle along the blade
including the sweep of the tip? How does the clamp work on hollow or convex
ground blades? Is there a weight limit, could you use it with a big bowie?
Can you just substitute in any bench stone you have?

Good bunch of questions, Cliff. I will answer each question one-by-one.

The frame gap is the limiting factor, and it is 5 mm, less than 1/4 inch.

Since the burr, once produced, is immediately wiped off by the other
hone, it is hard to detect. However, once a blade is sharp, a small
burr is detectable.

In theory the v-sharp

Both sides at once is a crock, pardon the pun. The two hones strike the
edge about 1/4 in. apart, so it is always one then the other, and the
far hone can never reach the bolster. For that matter, the near hone
also misses the bolster by about 1/4 in., and the far hone leaves 1/2
in. unsharpened.

The stroke is only about 3 in., so it is not well suited to extremely
large knives.

The V-Sharp is somewhat easier to use if you don't want to change the
angle or hone. Crock sticks are more versatile, especially if they have
two or more different grits, and the SharpMaker is even more versatile
with triangular rods and three grits available.

I tried a variety of knives and did not see any adverse effects, but
could not vouch that any of them were optimal.

The Hunter guide has one more degree of freedom than the Skarb guide, so
it controls the angle better. Also the geometries are larger, so the
relative change is less. The angle does become somewhat more acute
toward the tip of a straight blade, but an upsweep actually reduces this
effect.
How does the clamp work on hollow or convex
> ground blades?
It is a fairly conventional clamp, similar to a Lansky, with a 3/4
throat and two notches to help locate small blades. Works about the
same, some care is needed.

Is there a weight limit, could you use it with a big bowie?
You might want to fasten it down for a really big knife, but basically
the weight of the knife rests on the stone.

> Can you just substitute in any bench stone you have?
It basic Hunter comes with a 6" stone, and any 6" stone would fit. The
longer diamond hones have a notch at the 6 in. mark of their wooden
bases, which allows them to be used.

That is nice, it allows for ease of expansion.
