I would like a longer set of jaws that could hold flexible knives and make them inflexible during sharpening. Fishing/boning knives can be done incrementally, but I would prefer to get longer strokes on the blades.
Thanks for bringing that up. I’ve been slowly working on that concept but your post just gave me a good idea that I’ll try to pursue.

I’ve had good success just using the stock spine support rod that fits into the frontiof the we base… It keeps it rigid enough and works well I think
We can’t use that rod if we upgrade to the ball joint arms as the included riser lifts the knife too high.
I wonder if Clay has ever used two vise clamps to hold a knife?
Might simply mount two arms each side of my bench vise. 
I have a great and simple idea I’m going to try tomorrow. How about an extender on the support rod? I’m going to cut a short chunk of dowel rod, drill a hole to fit on top of the extended and file a 'v ’ notch on top. If it’s too short a few layers of masking tape will match the heights. It seems too simple to work…
More on this tomorrow…

If it works, maybe get machined in metal for longevity and durability…?

Riser? Could you post pics? Haven’t seen this yet I don’t think…

The block is an ~ 1 inch tall addition that comes with the upgrade arms. It installs at the base of the vise triangle.
Take a look here
So the “riser” doesn’t actually raise the knife higher… Just the base of the rod arms, right? And how does this affect being able to use the stabilizing rod for fillet knives? I don’t see how it would make a difference…
It raises the vice effectively lengthening the “pivot point to blade edge” distance, but in doing so it raises the knife higher above the base making the stabilizing rod too short, unless you take and rotate the tip of the knife downwards in the vice, which will possibly introduce some funky angle changes on your bevel.
Does that help or have I really confused you now?

No that totally makes sense… I looked at the picture again and had not seen the vise riser before. Has anyone tried using the new arms with the vise with no riser under it? If s , what is the minimal angle without the riser block?
I’m not sure. I just got an email saying mine should be shipping by the 17th. I imagine it would be around what it is with the stock arms, but the the angle dimples are not going to be correct using the new arms without the riser. With an angle cube it should be doable…
Ah sweet, so the easy cheapest fix to this is just getting an angle cube it sounds like let us knowionce you get yours in!
Hi Josh, it’s not so much that the angles may not be the same without the riser.
It’s more to do with the length of the stroke with the stone using the the new arms and “no” riser.
You can see in the pics that the top part of the stone can’t be used.
Compare the lengths.
It seems the riser was included to allow the ball joint addition.
See point “A” is roughly the same.
The new crossbar was added for a couple of reasons.
The first being a “belly” was found on the old crossbars and the tighter fitting new “L” bracket wouldn’t fit.
The second was the ability to achieve more acute angles (13°) and therefore an angle dimple location revision.
While this thought was going around, a longer crossbar would also offer 35°.
I would like to try an even thicker riser and longer arms.
So the full length of the stone can be used.
When you say “cheapest fix”, you are aware what comes with the ball bearing upgrade kit?
I am working on a solution to support/strengthen the hold on a flexible knife.
I see the ProPack II is still advertised as having the knife brace feature.
I see a quick look by Clay at a paddle you can attach a rod, back in 2011.
Wonder where this idea went?
I’m still working on that, it’s actually very close to completion.
Is it also the solution for serrations?

It is one of several.
So the “Coming Soon:” list on page 11. of the user guide are still in the works?
