Review on 100PCS 9Mm Carbon Steel Utility Knife Replacement Blades, 30 Degree Snap Off For Retractable Cutting Knives, Hobby & Craft Knife, Box Cutter by Andrew Mack

At only 18 cents a blade these are so much cheaper then OLFA which runs about 70 cents a blade, so its about a quarter of the price. I have to admit they are not as sharp as the former so this might not be the best choice for really precision cutting but for general utilitarian use these are great. They are very sharp and cut clean and effortlessly on thinner materials. The blades seem to be more flexible the others so use with it extended out is not ideal. Comes in a nice blade holder to safely transport your extra blades.
