Who owns eg Ledertaschen- or backpacks, sails, rides, surfing camped or has otherwise to do with rich fabrics or leather, knows that: seams burst sometime on or tear. With a conventional sewing machine is then not align. At most, pliers and coarse needle can still help with thorough cursing. Happy ending with some broken needles, and sore fingers. With the awl saves you cursing and injuries to the hands. How does it work? First, wrap the yarn supplied to the small metal coil, pull thread through the eye of the yarn brake, insert the needle into the "chuck", screw, Thread the thread into the eye of the needle - that's it. Sewn is: awl pierce the thread through the material to be sewn. Then pull the thread through generous on the other side of the material, so that a so-called lower thread in over-produced seam length (work generous!). The bobbin thread hold and pull out the awl again. The next trick set. Then pull the lower thread through the loop, which arises when one withdraws the Ahle something out of the pierced material. The Ahle finally pull out entirely and put the next trick. Sounds complicated? But it is not. In principle, the result is a seam similar to the one that gives rise to a sewing machine with its upper and lower thread. Or whom the comparison to explain the procedure does not work, here is another: The lower thread is pulled similar to weaving through the upper thread loop that inevitably arises when piercing the material with the awl. The result is a heavy-duty, clean seam with a little care. So much for the procedure. The awl is also an instruction manual. Frankly, I think the drawings for confusing than my above description. But that may be a matter of opinion. On YouTube you can find an excellent video tutorial [...] to deal with the "Awl", eliminates the last ambiguity when handling. And the product? The awl is made of solid wood. Unlike other models, the bobbin is not in a hollow handle, but directly forward over the needle seat. I find this very handy. With the thumb can be so easily the thread brake use (so the thread not by piercing and pulling out uncontrollably wegflutscht). The handle part is working well, the "chuck" takes the needle to clean and keeps them firmly. After first appearances I have to say: a 5-star product. And incredibly practical! Tip: If you have threading the lower thread in a sewing needle rough it easier to pull the bobbin thread through the loops.
