  • Works great.
Size: 4" Set name: Flex
Very flexible and very well made.

  • Sharp and Durable
Size: 3" Set name: Stiff
I recently purchased the scraper to use for removing parts from my 3D printer, and I have been very impressed with its performance. The scraper is well-made, durable, and has a sharp blade that easily cuts through any residual adhesive or material left on the print bed. The scraper is a simple but effective tool. The three-inch blade is the perfect size for my needs, and the black handle is comfortable to grip and provides a good amount of leverage. The blade is made of sturdy metal, and it holds up well to repeated use. One of the things I appreciate most about this scraper is how easy it is to use. The sharp blade easily glides under the parts, and with a little pressure, the parts come off cleanly without damaging the print bed. It has saved me a lot of time and frustration compared to using other tools that were not designed for this purpose. ... show more

  • Great tool
Size: 1.5" Set name: Flex
Exactly what I expected from this putty knife. Great quality with minimal flex which makes proper application and even scraping a breeze.

  • Good Putty Knife, Terrible Label
Size: 1.5" Set name: Flex
In the year of our Lord 2025, how is it still possible that the adhesive used in product labels can be so devilishly difficult to remove? The product is high quality and would get 5 stars if it weren't for all the lighter fluid needed to get the glue and shredded label off the blade.

  • Versatile!
Size: 1.5" Set name: Flex
Great value for money, works for various things other than what I needed it for! Easy to use and hasn’t broke on me. Great size too!

  • Great for small projects too!
Size: 1.5" Set name: Flex
I bought this for a putty hole project I was doing for weighting my chess pieces. It is SO handy! It fits my big hand perfectly as well. It's nice and sturdy, yet bends when you are filling the holes. It has a nice grip handle and cleans up well.

  • Perfect flex
Size: 1.5" Set name: Flex
The Red Devil flex is just about the most perfect putty scraper that you can buy. The blade has the perfect amount of flex. I had bought some other big name brands, but this is "the one" to own.
