Gomake 100PCS 9mm Box Cutter Knife Replacement Blades 60 Degree Carbon Steel 9mm Snap Off Blades,Fits Most Retractable Knives

For some reason these blades always come up first whenever you type in Olfa or Tajima. Very annoying -THEY ARE JUNK. If you work in a trade where you have to change blades frequently these simply won't do. It will take a long time to snap off a blade. You can't do it with a dispenser like you can with Olfa or Tajima, you have to go get a pair of pliers to break the tips off. The manufacturer simply doesn't score the metal properly between each tip. I hope Amazon will be able to read through the hype and understand that these blades are in no way an acceptable substitute for Olfa or Tajima or even many other lesser known brands of snap-off blades. THEY ARE LEMONS. This was a returned item, so be ready to use Amazon's very nice return policy if you have been fooled into buying these blades.

I've used and purchased many Olfa blades in the 23 years of window tinting, I thought I'd save some money and experimenting with a cheaper alternative, you really get what you pay for.I can't count how many dull blades I got from the pack and how frequently I have to snap off blades to get a sharp blade. Not worth it.

I do window tinting , and do not recommend these for that they dull out quick and tear into the film and can also scratch glass...not good...

I normally use Olga stainless steel blades, these were a great deal so I figured give them a shot. I am a window tinter so I use these all day long, I burn through these blades 3x as fast as an Olfa. They dull very very quickly and are not the best quality but they do the job.

I usually use a utility knife, but need very sharp tips to get clean cuts. So speed up blade changes, I thought I would give this 9mm replacement blade a try.New out of the box, they were more dull than the utility blades I throw out! You can usually see that they are not sharp at all. Not sure if I got a bad batch, but as they are it’s useless for my needs.

I read the reviews and thought people were just being super picky, they weren't.While they aren't completely unusable for me these are the least sharp razor blades I have ever used, in the future I'll pay a bit more for better ones

These blades will scratch any glass surface. Great for cutting window tint but not recommended to cut on the glass.

Great blades! A great replacement for the VVivid tight 30` angle blade vinyl knife.
