The Original Tumbler Rolling Knife Sharpener™ - Knife Sharpening Made Easy - Knife Sharpener Tool for Kitchen Knives - Knife Sharpener Kit Offers 15 & 20 Degree Sharpening

I was dubious about this sharpener, but after receiving it as a Christmas gift, I'm thrilled with it! I have a Work Sharp Ken Onion series grinder that I've used for about 12 years now, and it does a great job...but...it takes up a lot more space, and is a lot more complicated. Once I got my Miabi 8" sharp using the 15º angle and rolling the stone against it about 25 times on each side, now about one every other week, I just hone it or give it like 5 rolls on each side, and it's perfectly sharp all the time. Just sharpened my pocket knife yesterday as well. Most of my knives are either Japanese or Japanese style, so the 15º side gets used a lot, though I have some older German knives that I sharpen at the 20º angle. Only thing I wish is that you could replace the head if it gets worn...hasn't been an issue yet, though...my Work Sharp, you can buy new belts for when they wear out...

Wow. I had gotten used to the sharpness (or lack thereof) of my chef's knife, until I friend spontaneously gifted me another, and I discovered how much sharper it was. I'd heard about this sharpener, and decided to try it - the results were astounding. My old knife was now suddenly actually sharp again!

I like how quickly it restores the edges on my Wüstoff cutlery. The dual ended cylinder for sharpening and honing is great. I feel like the magnetic block could be wider so that longer knives have more lateral stability when sharpening. Also, sharpening smaller knives like paring knives or knives with less blade height is challenging.

I was genuinely impressed by how sleek and well-made this Tumbler knife sharpener is. The packaging alone gives a premium feel — it comes in a beautiful orange box, and the wood-like finish on the sharpener itself adds a nice touch of elegance to my kitchen counter.Most importantly, it works incredibly well. I used it on a few of my dull kitchen knives, and in just a few strokes, they were back to slicing like new. The sharpening process is smooth and safe, and the tool is very intuitive to use.Compact, stylish, and highly effective — I highly recommend this to anyone looking for a reliable and attractive knife sharpener!

OMG it actually works!! I took an old 4” paring knife (which I had successfully sharpened down to a dull butter knife edge using other pull through type sharpeners) and brought it back to a very sharp useable knife. Highly recommend!! Works great.

Been using this sharpener for 6 months. It's fast and does a great job of honing the blade to a fine edge. I'll be buying for the boys!

Great but the diamond stone can't be changed after it stops cutting into the steel. Tried to reprofile and sharpen a new knife after doing my entire block. Took 30 minutes to get a burr. Used to take 5.

First use was good, I was able to restore a few of my nicer kitchen knives. Two German steals and one Japanese Damascus knife.
