Of the Lansky type systems the best is meant to be Edge Pro. A number of small but good custom knife makers here use them. There is a guy Frenchy over here who has some nice bushcraft knives and he rates them highly. I think Unsub has got an Edge Pro so maybe he can chip in.....

I am suprised you have worn out a Lansky stone though.....I have their "very coarse" diamond stone which I use for re-profiling....compared to how rough it was when I first got it....it is pretty smooth now....but not worn out...and that has re-profiled a lot of edges.

I tend to use a combination of three now....I reprofile accurately on the Lansky....then use a marker to make sure I am not removing the fine edge I put on the re-profile and take the blade to a belt sander just to convex off the V grind by rounding the edge profile not necessarily going for a sharpening to the pinnacle...just curving the edge like on a secondary grind to thin it out...and I check the marker to see if I have rolled over the pinnacle...if I have then I use a leather paddle and green buffing compound to bring back the razor edge but this time it is "convexed" and should last for the lifetime of the knife if you top up the use on the edge by frequent paddle stropping.

This seems to work best for me. Trying to get a "razor sharp" edge on the sander by changing belts etc was doable but it removes a lot more metal than I want to and it is very "hit and miss" for me on the "razor" aspect because you can roll over the edge...but the paddle is excellent and you can easily use this to bring it back.

Most of this I got from HD on what he does....he does'nt re-profile though on a Lansky....but goes straight to the belt sander....for me I like to know the angles on the edges before convexing....I think the liklihood of putting too thin an edge on the blade is too high if I did'nt go this route.

So far it works a treat....the paddle and compound was the missing bit or the last bit I added to the regime....cannot recommend this enough....so easy to get an amazing polished razor edge. Beats using light strokes on a Sharpmaker by a mile which is what I used to do.
