Scraperite® double-edged plastic blades and one holder. This original patented double-edged design is best for corner access and straight line scraping. It is the workhorse of the line, the blade series that helped build the brand and remains a key tool in many applications. These blades naturally lift dirt up and away without picking up germs and can be easily wiped with a disposable cloth after each stroke, unlike scrubbing pads and sponges that collect dirt with every pass.
Three distinct colors indicate the blade's hardness.
The Orange General Purpose (GPO) blade is a forgiving material soft enough to be used on most soft surfaces like other plastics, thanks to its natural lubricity and pliability. It also has good resistance to household and industrial chemicals making a great all-around blade for general use around the home or workplace. This resistance to chemicals makes it ideal for removing decals with chemicals like acetone used to quickly break down the acrylic adhesives. This material is approved by Alcoa and Boeing for use on aircraft alloys.
The Blue Medium (MBL) blade is a durable and flexible compound that stands out by its resistance to harsh chemicals like bleach. These blades provide a balance of pliability and strength, conforming to curves and rough surfaces with slightly better resistance to edge wear than the Orange blade. Good on ceramics and stone as well as laminates and vinyl, depending on chemical used.
The Yellow Hard (HYL) blade is made of a hard and more brittle material and is the most rigid. Its low flexibility keeps it flat when removing stubborn substances from hard flat surfaces such as glass or tile but is more prone to breakage under vertical pressure. This characteristic also increases edge durability under similar circumstances compared with other blades. Solvent must be carefully selected to ensure blade material will not break down.

Works well for removing proseal from surfaces without significant scratching.
Great all - around blade. Used for corrosion removal, RTV removal, grease scraping, etc. in automotive and aircraft projects. Every shop should have some of these!
Picked this up the scrape labels off of aluminum parts from Zenith. Wasnt sure whether to use the orange or yellow blades. Yellow ones chipped on the first use, but the orange ones (this item) are working really well!
This product comes with 25 double-edged blades and 1 holder. There are 50 usable edges per pack.
