Carving a net needle from wood is probably easier than you think as long as you have your trusty Swiss army knife at hand. It has a wide array of available tools in a small unit. First you will need a piece of balsa wood. It should be 1/8 of an inch thick by 3 inches wide and 8 inches tall. Using the sharp narrow blade of the knife, you will cut 3 reference holes in a triangular pattern. The points of the triangle should be 1 inch apart at the bottom and the triangle should be 2 inches high. You will then proceed to cut away from the triangle, leaving a point in the center of the wood. At this point you should have only removed 1/4 inch of wood around the remaining point. You will then need to notch the bottom of the wood (which is the side that the point faces away from). Once you have notched the bottom, you should round the remaining posts. Above the bottom notch you will then need to carve the sides slightly inward about a half in on either side. Now, for the top, all you need to do is shave the wood to an aggressive point. Make sure the top is sharp and uniform all around. This completes your net needle and remember to utilize as many tools your Swiss army knife offers. Each one is more suited for each part of fashioning your net needle.
