For the money and depending on the amount of sharpening you are going to do you might want to look at one of the other rod guided systems.
I am partial to the GATCO.
For ease of use and relative cheapness I have a GATCO professional kit. I added their extra fine and ultimate finishing stones. Then I have $2.00 in scrap leather from Tandy that I load with the white and red polishing compunds from Sears. The compounds were under $5.00 for the two sticks.
After the GATCO and stropping I am very pleased with the edges I can produce.
The GATCO will do 11°, 15°, 19°, 22°, 25°, and 30°.
I have sharpened all of my kitchen, hunting, fillet, and folding knives. I have also been doing knives for the guys at work. They seem pleased with the results of my system.
One guy told me he caught himself four times with an edge that I produced for his deer knife. I guess he didn't learn quick nor did he listen when I told him to be careful.
