Shimano Biomaster SW 5000XG. Purchased new and has been overhauled once. Used on rocky shores and breakwaters, so it has many small scratches. However, after each use, it was washed and dried in the shade, and since it's a model with an oil injection system, I regularly applied oil. Therefore, there is no gritty feeling. I personally think it's still usable, but please understand that it is a used item before purchasing.
