"An Ax to Grind: A Practical Ax Manual"

"Putting your nose to the grindstone" implies tedious, repetitious, and unending work.
You will find that sharpening a dull or abused ax is indeed tedious and repetitious, but
to do it right you have to do it slowly (Figure 62). Along the way, you'll learn the value
of patience, and appreciate the differences in steel tempering and ax quality as you
sharpen different axes. Best of all, you will appreciate the usefulness of a razor–sharp
ax, and the importance of doing everything you can to keep it sharp.
