Until now, I had only used a scraper like a toy. Olfa made it easy to use because the grip part is hard and the thickness is moderate, the tip is thin and you can also work fine work. I feel that the L type faces towards objects that do not need much force. I think that most work can be done if S type is used together. I used it together.
Since it is too sharp at the corner of the blade which I use for double-sided tape pasting from olden days it is polished and rounded off the corner and injured people will continue. It is useful if you have such products.
