Lansky Professional Sharpening System, it's a great product that does exactly what it says it will do.
With this system I've sharpened everything from a 3/4" penknife blade to a 15" Cutlass blade.
What it does is allows you to sharpen to an angle repeat-ably, and that is important for keeping a knife sharp.
You need no special knowledge and it comes with all the instructions. There's always YouTube for a wealth of videos on Lanskys.
Start with the coarsest hone and choose your angle (it's all explained) then go up through the grits to the finest.
I'd recommend a Super Sapphire Polishing Hone
for a polished edge and they now make a Lansky Sharpener's Leather Stropping Hone
to strop your final finish to scalpel like sharpness. You don't need them but they are there if you want the very best edge. There are diamond hones to get the edge faster but I always finish with the sapphire hone.
The one thing that isn't included and I think is vital if you haven't access to a vice is a Lansky Pedestal Mount
it makes the process of sharpening a lot more comfortable, I've got mine stuck on a cutting board and it is stable enough to sharpen long blades. If you are feeling like spending a bit more on a clamp then Lansky Super C Clamp.
would be a nice addition.
I've got a lot of money invested in my system and still want more, it's a damned good system that you can add to over time to build YOUR sharpening system.
The makers, Lansky, are quick to reply to emails as well - always a good thing.
