Superb system except one recommendation right of the bat. Make sure you upgrade to the ball-joint-arms from beginning if you can. The standart ones dont do the system justice.
I have sharpened like 15-20 blades so far and i get better with each try. Also depends if you want mirror polish at which point you will def need the 1200-1600 ceramic stones if you get a chance. There are better options (diamond tapes) but dont last as long and cost more over time. The ceramic ones are a better investment.
Gotta be a bit carefull with, tanto, big recurve, Fully flat ground blades.
Additionally no matter which WE system you get you will def need a angle cube because even if you out the arms on exact same angle on both sides the angles r not usually same and it negates the entire system if your angles are not same from both sides.
EDIT: most important thing get some cheap knives from a flea market if you dont already have some to practice on because of the learning curve. Also the diamond stones when new should be used on cheap blades because you have a lot of excess diamond dust on them that falls of on first few sharpenings. One of the most important things is to place the blade correctly. They have a pictured instructions make sure u read them
