This is definately the best scraper I've ever used.
It's bullet proof!
Has a heavy metal rod thro the centre, so clumping it with a hammer is no problem.
I will admit this is the new design and it has wider shoulders than the old, which personally I think hinders the performance a little because it can catch things when being used.
The blades are excellent and sharpest I've come across and sharp enough to shave with!
I kid you not!
Blades also come in two widths, and the wider one is flexible, which is great for wallpaper and paint scraping.
Not cheap tho.
Blades are about £6.00 for 10 but well worth it.
