Universal Grinding Gauge
By Benjamen Johnson
Not sure if you’ve sharpened your tools or drill bits to the perfect angle? This universal grinding gauge from Silverline Tools will help you check.
Made from heavy-duty 14ga stainless steel, the grinding gauge can check 55°, 60°, 90°, and 120° internal and 60°, 90°, and 120° external angles. Silverline manufactures their tools for the UK so the etched graduations read in metric.
Five bucks will buy you this gauge at Jack’s Tool Shed.

I see no external 120° and no marked external 90°, the presumed ones might not be exact. Also, why not make the shortest rule start from the edge and why two 120° angles, why not make the rightmost one more obtuse or acute depending on what applies most? Everything I own is sharpened by eye, tools that need accuracy don’t get used enough to warrant sharpening so maybe I’m just misunderstanding this thing.
