Good tool. My wife got it for me for my birthday, and this afternoon I used it for a marathon auger-restoration session where I sharpened two to three full sets of old estate-sale augers with it. No pinning of chips and very comfortable. I didn't give it 5 stars because it's too thick to get in between the spur and the screw tip of a #4 auger (Irwin and Jennings patterns both).. no problems whatsoever with #5 and up. I don't know if this is par for the course or not as I do not own the old Nicholson file. As it stands, this file comes recommended by me.
I own this product.
