Harbor Freight has a new Multipurpose Sharpener - which 'should' be useful for drills? SKU 99823 currently $39.99
I have seen other gadgets for twice that - that did not work. Looking at the manual one can not tell if this may actually is even likely to work.
Any experience or opinions? What may actually work for drills? For 50 years I just bought new ones when I was unable to 'hand sharpen' the old ones.
