Compact Frame: Features a small 6" overall length designed to fit comfortably in a tool apron, pocket, or small tool pouch for easy transport and rapid deployment.

Die-Cast Alloy Chassis: Built with a durable gray die-cast metallic alloy body that withstands jobsite impacts while staying lightweight for single-handed use.

Factory-Fitted Edge: Comes equipped out of the box with a 5-1/2" fine-cut blade (the exact tool body that holds the 21-398 replacement blades you indexed earlier).

Tool-Free Blade Swaps: Integrated with an intuitive rear thumbscrew tension assembly that allows for fast, tool-free blade switches or cleaning.

Trade Applications: Highly favored by tradespeople for shaping drywall/sheetrock edges, cleaning up laminate counter trim, profiling timber end-grains, and rapid wood beveling.
