This is an original carbide triangular scraper from our workshop. The length before sharpening is 30mm. There are two types: the right one in photo 1 has a shaft diameter of φ2 (actual measurement approx. 2.4mm), and the left one is φ1.5 (actual measurement approx. 1.9mm). This is a single item listing. Please determine which one it is from the title. Image 2 uses φ2, so please understand that it is a general length guide. Unlike the standard basic scraper with a house-shaped blade cross-section, this has a triangular pyramid cross-section of 60 degrees, making it a blade on three sides. It can be said to be an inexpensive scraper tip. The mirror finish provides excellent blade durability and sharpness. It is a versatile tool for chamfering and deburring plastics, modeling wax, urethane coatings, and other soft materials, as well as precious metals. Engraving chisels are mainly used for polishing work, such as scraping off precious metals, but since it is a versatile tool, I prototyped it for my own use in repairing urethane coatings on fishing tackle. Made from the highest quality domestic carbide material, and sharpened by me, it is, of course, a purely domestic product. Please be aware that Chinese products are not only poorly made, but the carbide material is also significantly inferior. Notes: φ1.5 has a thin diameter, and the taper is much sharper than φ2 to ensure the blade length, so it is not suitable for use on hard materials such as metal. The shaft diameter and color may vary slightly due to the black skin. The length may be shortened to about 28mm due to sharpening. The tip is pointed, so it will chip easily if bumped. However, the tip is not as sharp as a marking tool because it has multiple vertices. φ2 is close to the router shaft diameter, but it is not a scraper to be used in a router or to use the tip. Please use it with sufficient caution, including wearing safety glasses to avoid injury. This is a listing for the scraper tip only (cap included). The items in the photos are not included, they are mainly for illustrative purposes. Please understand that there may be slight differences from the actual product due to the use of images. Please use a pin vise or other method for the grip. φ2 is a little thick for a 2mm core holder, but it may be usable depending on the object. Initial defects are covered, but blade chipping or damage after use is not eligible for replacement. Angle adjustments are also possible during re-sharpening, and we will accept requests after purchase. Delivery will be via Mercari's Nekopos service, including shipping.
