I bought this system as I felt I had gone as far as I could with the Spyderco one. If used intelligently, this system produces a first class edge. However, don't think that using the system as suggested in the leaflet and online will produce consistently good results. You would do well to look at the article by John Juranitch which you can find by searching for his name or 'rasoredge'; this shows the importance of establishing a secondary bevel first of all, and for this you will need the extra coarse hone. Also, it pays dividends - and yes, I am rather obsessive - to use a jeweller's loupe (get one from an optician for a few pounds) to check when you have got a good secondary bevel. Once this is established, it shouldn't take more than two minutes at most to resharpen the blade.
