SVST Double Duty Edge Bevel - 91
A good quality edge sharpening tool for home use. (Don't use it on Magna traction though. Make sure you have a specific tool for that)
Mold injected from ABS plastic. This unique design holds both file and stone allowing the technician to sharpen and polish the edge with one tool. Both stone and file can be replaced separately. This bevel is set to 91 degrees.
