The Generation 3 Pro is our fastest and easiest-to-use sharpener. It has an angle range of 14 - 27 degrees with micro-adjusts that allow for 0.05-degree adjustments. It’s operated with a lever that sets both side angles simultaneously. It includes built-in shelving, a hard carrying case, and sets of the 100/200, 400/600, and 800/1000 Grit Diamond Stones. It is a large sharpener that is designed for heavy use, a dedicated workspace, and for someone who wants speed and convenience more than versatility. The WE130 has a wider angle range of 13 -35 degrees along with the micro-adjusts. It comes with the 100/200 and 400/600 Grit Diamond Stones. It’s a very versatile sharpener that makes it easy to sharpen asymmetrical blades. The WE130 is also significantly smaller and lighter than the Generation 3 Pro.
