Awesome blades. Very sharp, closet shave I've ever had.

These blades are super sturdy and sharp. They all come packaged individually within the box, which is as expected. I use these as hobby knives, which they work perfectly for. They're ridiculously sharp, so careful. I cannot attest to their use as scalpels for cutting flesh, but if the cuts in my fingers are any indication, they'll do fine.

Very impressed with the three blades. They throw the grass very well and cut really nice as well.

I ordered these blades on June 15th. Just installed them today, Oct. 24th. Very impressed. Very heavy metal. One was in perfect balance, the other was just slightly off, not enough to require work. Both blades required sharpening as expected.

They are expensive but they are very sharp and super quality.  Makes X-Acto blades look very bad.  Great for cutting film and decals.

I have used these blades before and have been very satisfied with their performance. They stay sharper longer then most other blades I have used.

This blade is a work of art as much as it is dangerous. Its gorgeously polished and sharpened to a hair popping degree. However its only real practical use is to kill something. Its not a woods crafting knife or utility knife, so its not very versitile. However I would not want to be on the recieving end of this blade in a fight. Worth every penny.

I received these blades in a timely fashion. The only difficulty I had was the viscosity of the lubricant that they use to protect the blades in package...took a little longer separateing than usual. They are very sharp similar to other titantium blades. I only used the first blade for an hour and it work very well the whole time. Looking forward to see how many hours per blade use.

Amazingly sharp and great to hold. Be careful as these are so sharp that the foods cuts itself when the blade comes in the vicinity.

These blades are sharp and cutting edge. They fit into my old fashioned American-made box cutter as though, well, they were made for them. How cutting edge are they? They cut better than a knife. Foam board, matting, paper, they all part like the Red Sea before the cutting power of these blades. I highly recommend them. Stanley heavy duty utility blades, they make knives look pass!

I cut myself almost immediately, but thats what happens with sharp blades. It does it's job quite well.

I did significant research on ceramic blades, and decided to start with the 5 1/2" Santoku, and the 3 1/2" Paring by Kyocera. The first time I used these knives, I was amazed at how sharp they were! I cut paper thin Tomatoes and Lemons, I could never get slices that thin with a good stainless steel blade. If you want to cut quickly, I highly recommend a Cut Resistant Glove. That way if you make a small mistake, you haven't cut half way through one of your fingers. Ceramic blades are much lighter than steel, so it's easy to start cutting quickly. The Y Peeler was a nice add on, and works great. - Highly recommend!

I had some standard Olfa blades left so I could compare them UltraSharp. I held a 3x5 card by one end and sliced  it with both blades. No contest!  The UltraSharps are considerably sharper. I'll be back for more.

These blades are sharp when received, and require very little touching up.  They can be used right from the package if you do not have the equipment to hone them.

These blades are sharper than the famous brand sold in the stores.  Really happy with the quality.  Will purchase again in the future.  Thank you for such a great product.  Exceeds my expectations.

Thought this was one blade I was purchasing but came as a set of 5. The blades are tool steel and extremely sharp!
