Customer Rating: 
Summary: Spend the extra $10 and purchase the Wusthof 2 Stage Knife Sharpener
Comment: Overall: fast, efficient and small but I question the safety and also the need to hone the blade after sharpening.
PROS:
1. Portability - small enough to keep in your tool- or tackle-box.
2. Fast - a few runs of your dull blade through this sharpener and you are ready to go.
3. Sharp - After a few runs, my kitchen knives were immensley sharper
CONS:
1. Safe? - I left a question mark on this one for two reasons: (a) The slot where you slide (to sharpen) the blade is very small opening. You need to take care that the blade is securely wedged inside and not sitting on top of the white plastic. (b) Inherently in the design you can see that your fingers and arm are inches away from a newly being sharpened blade. So long as the blade is securely contained in the wedge you are fine. I would have preferred to see the design keep the motion of the being sharpened blade in a direction pointed away from my hands/arms to feel safer.
2. Honing needed - This sharpener puts a nice edge on the blade but you still need to hone the blade afterward if you are looking for a finely sharpened edge.
IN SUMMARY:
I believe this is one of the most economical sharpeners on the market. For the money it does the job very well. I would recommend that you also consider very strongly the "Wusthof 2 Stage Knife Sharpener" as it looks safer and also includes a section to hone the blade as well. I will be returning mine for the Wusthof.
