HARDWIN Ceramic Single Edge Razor Scraper Blades 1 set（5PCS）, for Glass Stove, Cooktop and Adhesive Removal

Love these new bladed

These things are NICE! Very sharp, super sleek, and very effective. I prefer the trend to ceramic over metal and these a good value for a quality product.

I have had some great ceramic blades before but always remain skeptical about their durability. These razor blades are incredibly sharp and hold their edge well. I have been using them as scrapers and am very pleased with how well they work on flat glass. They scraped stuff off my stove that I’ve been trying to remove for months!

They’re a bit of an investment compared to metal and are thick enough that some knives won’t hold them well, but so far I’ve been happy.

These blades are amazing at scraping! I've used them to clean a ceramic cook top, and they cut through baked-on grime better than the countertop cleaners and plastic knives that are recommended. That said, they feel less sharp than steel blades for cutting. (also these aren't really the shape for a cutting blade). They fit like standard blades do, but as ceramics they shouldn't be used to pry. But as ceramics, even if the blade doesn't seem "sharp", they will still scrape well because there won't be any knicks like in metal blades.
If you understand their uses, these are great!

These razor blades are SHARP! They are the same size as a metal razor blade. I use these types of blades for breaking down cardboard boxes for recycling. They work just as well, slightly better, than the metal ones. I was surprised at just how long these blades last. I'm still using the same end of the blade for days now. So far, a single blade has lasted for the past 8 days of daily use. Not sure yet if the long time use will offset the cost of these blades.

These Hardwin Ceramic Single Edge Razor Blades (5-pack) give new meaning to the term "sharp as a razor".

The ceramic blades are slightly thinner than a metal blade, and not as flexible. However, they are unquestionably sharper. You should handle any sharp edge with care, but it wouldn't be wise to be careless with these. Safety is paramount when handling these.

While they are a bit pricey, you'll be hard pressed to find a sharper blade. I don't know how durable they are, but I don't generally abuse blades. They appear to be well made, and for my needs they are perfect.

These ceramic blades have proven to be very sharp and also very strong. The metal cross bar gives added strength. The ceramic is great in that your contact surface is not going to rust. And so far they’ve proven to be sharp. But honestly they’re not as sharp as metal blades. I’d say they both have their own purposes and I’m happy I tried these so I can use them in as many applications I can except maybe glass scraping where I’ll still stick with metal. And that’s because the metal for sure won’t scratch the glass but the ceramic maybe could. Also there is a flex to the metal blade and ceramic there’s not. It’s just a rigid sharp blade. So if that’s what you want to try or need these work and are also very refined in quality and well made.

I must be out of the loop… I didn't even know ceramic razor blades even existed, much less ever used one. This pack of 5 seems very sharp, and a few passes across paper cut very cleanly. The ceramic blade has metal across the top opposite the ‘single edge’ blade, making it easy and safe to handle. What sets these blades apart is the fact these are rustproof. Whenever I did wallpapering I always had many all-metal blades rust quickly and had to be discarded. This solves that problem! These seem best suited for cutting and scraping softer materials to avoid chipping the ceramic blade so I will follow that advice.

I had a project and needed to cut window film and ran out of normal blades. It was a pain, so I looked for replacement blades and found these ceramic blades. Wow am I super pleased with these. I did a quick test with the foam that came in the package and it cut like butter. Super sharp, clean cut, and a great deal. I’m so glad I found them!

These are a bit expensive for only 5 blades, but if you need a scraper in a high moisture environment, you're going to need these. I keep a razor blade scraper near the shower for scraping soap scum and hard water deposits off the glass, but the blades tend to rust quickly from the moisture. With a ceramic blade, I won't have to worry about rust.

They are very sharp. I opened some boxes with one of the blades and it went through the tape like a hot knife through butter. We'll see how long they keep an edge, but they should still be better than the steel blades with rust on them!

For some reason the bag had a tamper proof seal on it. Maybe this is a retail security thing for hardware stores? I thought it a little odd, but it's no impact on the blades.

Sharp and will last. No rust, don't need to worry about leaving these wet or in moisture. Great for scraping gunk off glass. Works really well. A scraper handle or blade holder makes it much more convenient and comfortable. Handle with care, very very sharp

✅ PROS:

- Very sharp
- Increased hardness helps retain edge

❌ CONS:

- More likely to break than bend under stress

I have a couple of double-end scrapers (equipped with a metal blade and plastic blade) and decided to use one of these blades to replace the plastic blade.

My first impression was these blades were thinner than I had anticipated. I had thought the ceramic blade would be thicker, but it makes sense for it to be similar thickness as the metal blade it is meant to replace.

These are definitely very sharp. As a test, I tried scraping a label off a plastic container. Where I had the blade placed at the proper angle, that worked fine. Near one end where the angle was slightly wrong, it began to peel up a layer of plastic. As I recall when using a metal blade, it wouldn’t cut into the plastic that easily.

Ceramic is a tradeoff in that it is harder and will maintain a sharp edge longer, but that same hardness also makes it more brittle. Press down to hard with a metal blade and it will be more likely to flex than break.

I would say these are best used with a double edge scraper, so that one can have both blade types at the ready, and chose the one that is best for the application.

I have a small scraper tool I bought a long time ago. These ceramic blades are nice and sharp right out of the box. The blade quality is very high and I was able to use it to scrape my cooktop to remove the food that spilled on the cooktop while I was cooking. I used very little effort compared with the metal blades I used to use. This also means that it's very important to keep the scraper tool out of reach of children. The blade is very thin, but strong. It works well to clean my cooktop effortlessly and it's the perfect size to replace the metal blades that came with the tool.

At a price of $13.28 for 5 blades, it's a great value for the money.

I purchased this single edge razor to use for post processing of 3d prints and found this an excellent product for several reasons. I wanted a non-metal blade that was as sharp as a traditional blade that I could use without the risk of damaging metallic build plates. I use a plate called a PEI Textured plate that is easily damaged by metal to metal contact. An extra bonus is if it could also cut small support materials made out of PETg, PLA, ABS, or ASA plastics and continue to hold an edge.
