These scrapers are small and thin for finer woodwork. The biggest one is about 5 cm long. They are somewhat flexible, which allows you to target smaller areas better. The rectangular scrapers had a bit of a rough edge, but this cleans up with a file. I have used them for removing old lacquer and some wood shaping. I must admit I was a bit surprised at how small these are when they arrived. Do not expect to do any major wood shaving with these.
