All depends on what you want to do, for maintaining and edge a sharpmaker works perfectly, for re-profiling and restoring an edge that is too far gone you will need a system that removes metal faster. Lots of options to choose from, none are idiot proof they all take practice to become good at. I've used the KME sharpening system for years, its a cheaper alternative to a wicked edge and can achieve the same results, but much better than a lansky in terms of build quality and consistency in my opinion. I suggest you grab a cheap lanksy and a spyderco sharpmaker and practice on some knives you wont cry over if you fudge the edge up. Big learning curve to sharpening, any idiot can get a bur and knock it of for a sharp edge, but it will take time to get effecient at it, getting a perfect, even edge on both sides without losing a ton of metal every time. Plenty of good info and guides on youtube, check some out. Cheers.
