Curved sharpening stones

[Scara]

So I was looking at Lansky's website, and I noticed that they have a set of curved sharpening stones that they say are specifically meant for sharpening inward curved blades like kukris and kerambits. Has anyone tried these to see if they're worth using?

It looks like they're the right shape to get the inside curve of a khukuri. Amazon is selling the same set for $10 less than the Lansky web site.

Lansky also makes a puck-shaped sharpener that should get the inside curve. It comes in a two-sided version with one side coarse and the other side medium, so that wouldn't give you the shaving sharpness that some people like.

I haven't had the need to sharpen the inside curve of a khukuri because that part of the blade gets very little use. A sharp khukuri makes an excellent draw knife (one hand on the handle and the other hand on the spine), and that's when the inside curve would be used.

A sharp kukri makes an excellent draw knife! You hit the nail on the head with that one david. The kukri is the BEST designed blade for a draw cut IMHO.

Actually I meant a draw knife for shaving wood -- the kind of draw knife sold in hardware and woodworking stores has a straight blade with a handle on each end. You clamp the wood in a vice and pull the knife toward you with the handles. A khukuri is much easier to control than those, and cuts really well with the recurved part of the blade. I don't know enough about knife-fighting to comment on draw cuts.

Hmm, I was picturing the same as davidf99 when I read drawcut. It is exceptional at getting long strands of bark for twisting into twine for survival, and making feather sticks ect... But GB's point is also valid, because of the way the blade angles a drawcut works awesome because the blade angles into the opponent on the pull. SO you both are right on the money. Back to the sharpening stones, anyone have any experience with them yet to offer feedback on if they work as well as they should?

I can't speak for these, but I did try out my traditional stones on my Reti, and the inwardly curved lower portion sharpened up better than the upper portion with the flat stones.

Yep that differential hardening. That inner edge is softer so will accept a great edge with less work, but has those other pesky problems of edge retention.
