I have to admit that after having a video catch my eye while visiting Cabela's that I sprung the money for a sharpening system designed by Spyderco, its their Triangle Sharpmaker. I got hooked into using Croc-Stix years ago and a buddy showed me how to make a pocket Croc-Stix from a huge parking lot style light bulb. I like them because after a day of use I like to stop by my workbench, take out my knife and give it a couple of wipes across my old Croc-Stix, keeps that baby shavin sharp. The Spyderco system works on the same method but does allow for serious sharpening of a dull knive as well as scissors and serrated blades. I have fooled around with Lansky's system and although have done some fine work with it and don't truly see anything "wrong" with it other than it as about as precise as using a good quality diamond stone set or Arkansas stones. I have turned some pretty decrepit blades around with Lansky but do consider it kinda imprecise when it comes to a really fine edge. Pretty tough to beat a good strop for that final touch, I did score a barber's stone a couple of years ago that is made from a red material and supposedly was used by them to sharpen razors, I have used it with an angle jig to sharpen my leather cutters.
