Wow, there's a lot of great posts here; I'll try to keep the standard
Sammy, if you're trying to pick between those two systems, I'd go for the Razor's Edge over the Lansky. Both the Lansky and Gatco are similar systems (I have a Gatco)and they both suffer from the same problem. If you don't clamp the blade at the exact same spot everytime, you will get a slightly different angle each time. The system certainly works, but I don't think it's that good-just my opinion and experience.
The Razor's Edge is good because you can use any bench stones, and generally there's a better sense of control. Now I have to admit I don't own a RE but a friend of mine does and he swears by it.
In other suggestions, there's the Spyderco 204. Great edges and fool proof; does serrations better than anything I've seen too. Only disadvantages are that is has two grits of stones only and two angles only.
If you really want to go all out, get an EdgePro Apex. In my opinion there is nothing better. A little more expensive, a little more practice required, but the results are worth it. If you want to know more, check out my review; Roadrunner has a link to it in his post. BTW there will be an update to that review in the next coupleof days.
Anyway I hope my two cents are some help. If your only choices are Lansky and RE, I'd go for RE.
