300 PCS Hobby Knife Blades

I decided to give these a try as they were inexpensive and I could use them easily unless they were total junk. Turns out they seem to be a little tougher than the genuine X brand blades. They are the same shape though a touch thinner as I had to tighten my blade holder a tiny bit. This isn't an issue, just an observation. Definitely an excellent deal since they easily replace the brand X blades, seem to be a little tougher with an equal sharpness. The bonus is 300 blades for $17. The X brand blades would run about $83 for 300 blades and they are not any better quality. I will definitely be buying more of these.

These are really not too bad considering the price and how many you get. They are obviously not as good as the name brand blades but they are definitely usable. The blades are 0.5mm thick which is enough for deburring plastic 3D printed parts which is my primary use for them. They are not nearly as flimsy as I though they might be based on some other comments. The edge is actually nice and sharp, I tried shaving some arm hairs, and the randomly selected blade that I used seemed to have no problem with that. Very similar to the sharpness of name brand blades. The edge of the blade is not perfectly flat though. There is a very slight concave curve to it. That isn't a big deal though, I can't think of any application for this type of blade where a slight curve would be a problem.

Exactly what I needed and so far decent quality.

Blades arrived quickly. We use them to cut sign vinyl and PVC and tested out just fine, no tip breakage. The only strange thing was the inordinate amount of oil coating the blades and saturating the oilpaper the blades came wrapped in. Will definitely buy again as the price was excellent.

Came in a tiny broken case, divided in three. the price is hard to beat but if you're someone who uses them daily you'll have to replace them often. They are sharp but dull easily I use them to cut transfer paper and they dull with a few hours.

They do the same thing as you pay many many times over for the brand name. They wear out just as fast, and now I don’t try to sharpen them. These are pennies per blade, and when you go to the home store you pay $10 for a few blades. They were packed in oil saturated wax paper. These will last me for a very long time. I would purchase again, if I’m still around when I run out (ha ha).

Pretty sharp work very well

It's a good thing they came in packs of 300. I used these to trim PLA and PETG flash off 3D printed parts. They fit into a standard exacto handle and hold well. The metal does not retain a sharp edge for very long. After trimming a few 3D printed pieces I could see the edge was already started to dull. I'm not doing anything crazy here, just trimming blobs, brims, or a little excess material to allow for the fit I need. But I'll go through probably one blade per set of parts. It may still be sharp enough to cut paper or something thin like that but it won't be able to safely cut soft plastic.

good product, fast delivery, great quantity for the price

Fast postage and super quality, will buy again from this seller ... :)

Sharp tools.

They're sharp and they cut.

I love these for most of my repairs. Be careful as these are very, very sharp
