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

My son ordered this for me for my birthday. It really brings a nice razor sharp edge to my knives. Pros: It is easy to use, sharpens well, and has a stone side, and a hone side. Can sharpen 2 different angles. Cons: If your blade is extremely dull, you may need a more aggressive sharpener, and it's too tall to sharpen steak knife size blades. you couldn't use it for a filet knife, or paring knife. Works only on larger kitchen knives. The blade has to be taller and longer than the alignment block, or you cant use it. its excellent for maintenance on sharp knives. Less effective for dull knives that need some aggressive grinding, or blades with chipped edges.

It works exactly like they described, definitely worth it.

Feels and works great. Seems to be worth the money.

This sharpener is a game changer. It’s simple to use and delivers an incredibly sharp edge without requiring any special sharpening skills. The only thing to remember is that it takes patience. I spent about 6 minutes on each side of the blade, and the results were well worth the time. If you don’t rush the process and let the sharpener do its job, you’ll end up with a razor-sharp knife. I highly recommend it to anyone looking for an easy and consistent way to sharpen their knives at home.

I have bought a few different knife sharpeners and used them all, each one of a different type. There's really many ways to go for sharpening your knife. Each providing a step up in sharpness, but also a step up in complexity to use (both in skill and time it takes to sharpen). -Honing rod (not exactly a sharpener but does make it "sharper" in a way) -Sharpeners with a v ceramic in which you pull -Rolling sharpeners -Belt sharpeners -Rod based sharpeners -Whetstones I think the nice middle ground for most people is either rolling sharpeners or belt sharpeners. I bought this really because sharpening with this is really simple, it takes barely any longer than the ceramic sharpeners and does a considerably better job. I think though, there are some big limitations... -For one, the magnet (that holds the knife) works great for wide knifes, such as chefs knifes... but is too tall to work for smaller knifes, such as utility knifes. >>Having a second smaller magnet as well would solve this. -There is only 1 single grit and a honing side. This works well for general maintenance, but if you have a heavily damaged knife it will take longer to sharpen and because there's no fine grit, you won't get that razor edge. >>Having a course and fine grit and a strop would be better... Or offering sharpeners with varying grits. These are the limitations of most rolling sharpeners out there... the next step up of using a belt sander, though can be found in compact sizes, it a little less "friendly" to use and wouldn't recommend it to everyone. Specially if you have a knife with a nice finish and worry about scuffing it.
