IRWIN Utility Knife Blades, Bi-Metal, 100-Pack (2084400)

These blades are much sharper and robust than any blades I have purchased in the past. It got to be such a hassle with replacing blades every time I used my utility knife because my cheapo blades would either snap or dull with each use. I finally broke down and paid for the quality, happy I did.

Excellent blades. Sharper than other brands. Better material and last longer.

Excellent quality blade that fits most utility knives.

I've been using Irwin blades for years, they arrive sharp and stay sharp for a long time compared to other brands. These arrive absolutely -soaked- in oil, so I don't suspect rust will be a problem.The case is difficult to extract blades from. The new version of the case has NO bottom slot, so you must extract a blade from the top and bang the bottom up to keep the blades feeding. The "slider" on the case arrived slightly cock-eyed and I had to disassemble it to get the blades feeding at all.

Great blades. Have used them for years. Best for breaking down boxes or just general cutting. There might be some confusion about whether these blades are the newer ones with the blunted edges (childproof) or not, so I am including a picture of the actual products received.

Update: I added pictures to clearly point out my conundrum with the complaints.Original: I saw a ton of people complaining about the "difficulty" of extracting a new blade from the Plastic case.- I have a feeling that people are either -1. Trying to get a blade out the top slot (You can see it's marked Trash) or2. Using the correct bottom one - but didn't see the access area cut into the bottom (see pictures)*If they have - and still feel that way - then they're even more ridiculous. These are RAZER BLADES... The fact that they don't just slide out of the case, by simply breathing on them, is a benefit.*Otherwise you'd end up with 50 loose blades - which would obviously be extremely dangerous - and they'd also all be ruined.*There is a thin coat of oil on the blades (which protects them from rusting and dulling) and it does give them the slightest resistance (because it causes them to stick together). But that's why the bottom access is there. So you can just use your finger (or nail) and push one out...Anyway, I think this case is a wonderful design. So seeing all the negative, I'm assuming ignorant, reviews about it really annoyed me 😒I hope this helps - oh and if it does please mark it that way, so more people are aware of this.PS The blades are good as well 😂

I love the price and how sharp they are, makes life so much easier when installing carpet

Edit: Rust. I just have it on a simple keychain utility knife which does expose the side of the blade, but it's not like I have a lot of moisture or stick my hands in my pocket so it seems to rust easily. Low volume use so can't tell if it affects performacnce.I got these on sale for a keychain utility knife, I didn't know what razor sharp was until I tried them, the one that came with the utility knife was definitely much duller in comparison. For anyone who doesn't want or need a full sized pocket knife these will work great and you don't have to be concerned about sharpening.
