Bests & Worsts Reviews from Amazon

Let me first say that I sell and work on knives for a living, so I know what I'm talking about, I'm not solely expressing my opinion as a "knife guy". I picked this up on a lark as I have tried multiple pull throughs, including most popular one's here on Amazon. That being said, this little guy is actually better than either Lansky's or Smith's current basic offerings, if you can believe that. I just used it to sharpen a Kershaw Filter, and now my inner left arm is clean shaven, with no irritation. This impressed me, as it only took about 5 minutes, and it looks to be set at a 20° angle correctly on both coarse and fine options. I haven't tried using the ferro rod combo, so I can't attest to it's functionality. The whistle, however works quite well; my beagle agrees. Overall, I'd have to recommend it if you're looking for a good pull through that won't chew up your blade. Good value for the money, too.
