A good starting point is to identify the differance between a market and crook walking sticks, once this was quite straight forward with a shepherds crook was very much by sheep farmers while a market walking stick more embellished product, a walking sticks showen off at markets and special occasions. Over the years the simple differance has become blurred.
A simpler way to distinguish between them these days is by the lenght of the shaft. Remember the orginal purpose, crook walking sticks will always be longer than market walking sticks, with 52 inch for crook walking sticks and 48 inch for market walking sticks.
For market walking sticks the profile of the stick is described as a nose in variety. To produce these walking sticks you need to obtain a suitable shaft length, a minimum of 48 inch growing from a branch or root of acceptable diameter about 4 inch as a angle of about 40 degree's. For crook walking sticks its mostly the same but with a longer shaft of 52 inch and the same amount of branch or root at a diameter of 4 inch.
