ALVIN ALT18 Aluminum Graduated T-Square, Drawing and Design Tool for Students and Professionals, Great for Carpentry, Drafting, Architecture, Engineering, and Art - 18 Inches

The high-impact ABS molded head T-square is a low-cost engineering plastic suitable for structural applications due to its strength, stiffness, and impact resistance. It is an easy to machine and fabricate material and provides excellent dimensional stability and ease of paint and glue. The tool is extremely durable and has excellent aesthetic quality. However, the plastic handle may not be as durable as expected. The tool is not heavy enough to stay in place when drawing and needs to be held with one hand to avoid sliding. The plastic part measures 9 inches, and the metal is 18 inches, making it perfect for mat cutting. The product has mixed reviews, with some reviewers complaining about the quality and durability of the tool. While others noted that the product was good for occasional use, it wasn't worth the price. Professional artists recommend this tool for its convenience and suitability for thick materials or on a stack of materials.
